I. Introduction
ut of the numerous dasha
systems used for prediction in
Vedic Astrology, the
Vimshottari and the Ashtottari dasha
system are two of the most popular and
most widely used systems. Although no
authoritative text or work may be cited
in which a clear logic has been
expounded for the dasha period or dasha
sequence of these systems, an attempt
has been made in a recent work1 to
highlight some interesting observations
and striking features of Vimshottari
dasha system. In the present work,
similar observations have been noted
for the Ashtottari dasha system.
In the present work, the two
luminaries, the five planets and the two
lunar nodes have been referred to as

simply planets or grahas. The Ashtottari dasha2 is a conditional dasha and is supposed
to be applicable when:
a) Rahu, not being in Lagna (Ascendant), forms a square or trine with the lord of Lagna.
b) When the birth is in the daytime during dark half (Krishna Paksha) of the Moon and in
the night time during bright half (Shukla Paksha) of the month.
tarting from Ardra, the nakshatras (constellations) are counted up to the
constellation of birth in the sequence four, three, four, three and so forth. Sun,
Moon, Mars, Mercury, Saturn, Jupiter, Rahu and Venus are the lords of
successive dashas. Six, fifteen, eight, seventeen, ten, nineteen, twelve and twenty one
are the duration periods of the Mahadasha planets starting with the Sun. This dasha
period is for the total stay of moon in all the nakshatras owned by the planet taken
together. The total dasha span of Ashtottari dasha is 108 years.
In some texts3, the second condition is not mentioned. However, in these texts the
counting for the dasha begins from Ardra when Rahu is conjunct with another
planet(s) and from Krittika when Rahu is placed alone.
The motif developed in the earlier article about Vimshottari Dasha System (viz. that
of dasha system being dependent upon the orbital motion characteristics of so-called
rival grahas) has been carried forward in this one too, and the observations have been
noted for each planet in Section II. It has been proposed that the Ashtottari dasha
system was developed from the planetary catastrophic era model and the interesting
resemblance between the dasha periods of planets and the planetary conditions
supposed to be existing during planetary catastrophic era (following the principle of as
above, so below) has been brought out in Section II.
II. Observations
e draw upon the ideas already developed in the work on Vimshottari
dasha system and the same are briefly reviewed in the following, for the
sake of completeness. As discussed in the referred article, the dasha
period of each one of the planets is shown to have a strong correlation with the orbital
motion characteristics of its rival grahas. Planets form such rival pairs by virtue of
being lords of houses or signs opposite to each other or due to their natural enmity.

It may also be recollected that each planet in a rival planet pair is seen to determine the
dasha period of other planet in the pair. As such, both the planets are loosely called
rivals in this work even though naturally, they may not be so.
Further, it is to be remembered that the dasha period is given in full years
corresponding to the solar return point at the start of the dasha period. Reader is
referred to the earlier article for a definition of synodic period and orbital period of
planets. The present orbital periods of planets round their parent body and synodic
periods relatively to Earth as seen from the Sun (or relative to Sun as seen from Earth)
are given in Table 1.

The observations for total dasha span, conditions of applicability, dasha sequence and
dasha periods of individual planets are given below.
-
1. 108 Year Span
A few observations may be made for the 108 year span:
i. It is known that the synodic period of Moon is 29.5 days. Also, Venus (Shukra also
means semen) is supposed to be responsible for life and the first month after
conception is ruled by Venus. Now, during the time it takes for human birth to take
place or gestation period to end (approximately nine months), the Moon completes
around nine synodic periods or lunar months lasting from one New Moon to the next.
The Moon and Sun are both enemies of Venus. Jupiter who considers Venus as its
enemy fulfills the same role after birth as done by Sun and Moon before birth. The
Earth, Sun and Jupiter again align at the solar return point after 12 years when Jupiter
completes 11 synodic periods (11*1,092 years). For Shukra, the total span of 108 years is 9
times this 12 year solar return synodic period of its rival, Jupiter or after approximately
9 orbital periods of Jupiter.
As elaborated later in this section, it has been conjectured in literature4 that before
about 701, BCE5, the orbital periods of most of the planets were in perfect ratio. The
earth year was 360 days, orbital period of Mars was 2 years, that of Jupiter 12 years and
Saturn 30 years. Also, the Moon took exactly 30 days for one revolution around the
earth and 12 lunar months made up one year. Then, the gestation period would be
approximately 9 ancient orbital periods of Moon and life span after birth would be 9
ancient orbital periods of Jupiter or 108 ancient years.
ii. It is known that solar or lunar eclipses of similar characteristics occur every 18 years
also known as Saros period. The moon completes an integral number of synodic,
anomalistic and nodical months during this period. The next similar Solar eclipse
moves 120o in longitude and a time of 54 years is required for it to come back a full
circle to the same geographical region (viz. Triple Saros or Exeligmos). 108 years
corresponds to two (ahoratra or day and night) of such Exeligmos or 6 of such similar
eclipses around the globe. The path of each eclipse, one Exeligmos apart, is about 950
km away from the previous similar eclipse in the series, and two Exeligmos would
cover around 1900 km, about twice the length of modern Egypt or Greece. The angular
separation between the Moon and the lunar nodes increases about half a degree for
each eclipse occurring after one Saros period and would increase by about 3 degrees after
108 years. The dependence of applicability of Ashtottari dasha upon Rahu and the
preceding discussion about eclipses is noteworthy. Also, the fact that 54 years is a trifle
short for Purnayu (full life span) and not divisible by 12 (Jupiter's orbits) could have 4Donald W. Patten and Samuel R. Windsor, The Mars-Earth Wars, Pacific Meridian
Publishing Co. 5 BCE is the abbreviation for Before the Common/Current/Christian Era (an alternative to Before
Christ, abbreviated BC)
-
prompted taking two of these Exeligmos together for a total span of 108 years.
iii. One of the most compelling arguments in favour of 108 years dasha span is provided
by the hypothesis of planetary catastrophism as put forward by Donald Patten et al6 and
Velikovsky7. In this planetary catastrophe hypothesis, it has been shown that the
numerous catastrophes that befell the earth have been recorded in various accounts of
ancient books such as Genesis, the Vedas and others mythological texts. These
catastrophes have been recorded at least from October 2484, BCE, starting from the
flood of Noah, and include the destruction of Sodom and Gomorrah, the Exodus of
Moses, the long day of Joshua and so forth, up to the rout of Assyrian army at
Sennacherib in March, 701, BCE. Various catastrophes are shown to have occurred in
Asia-Europe at a regular interval of 54 years or its multiples, either in October during
day time or in March during night time. The time of day was reversed for catastrophes
observed in America. The period for successive October daytime (night time)
catastrophes in Asia (America) is thus 108 years. This daytime and nighttime
occurrence of catastrophes could have relation to the time of birth being one of the
conditions of applicability of Ashtottari dasha in one's chart.
These catastrophes have been speculated to have their cause in the close fly-bys of
Mars that had a different and a much more eccentric orbit before about 701, BCE. It is
postulated that Mars acquired this catastrophic third orbit as named by authors, due to
its collision with the planet then existing in between Mars and Jupiter. Jupiter might
be responsible for perturbing the orbit of either planet (perhaps directly or by diverting
a comet) and putting it on a collision course with the other, in effect leading to the
destruction of planet orbiting between Mars and Jupiter and the subsequent formation
of Asteroid Belt.
In the previous article on Vimshottari dasha, by comparing the dasha sequence,
existing sequence of planets from the Sun and the appearance of Rahu dasha in
between Mars and Jupiter Mahadasha, it was conjectured there that perhaps the
asteroids have been referred to as Rahu in the ancient texts. The fragmented nature of
asteroids, retrograde motion of Hilda asteroids had also supported this view. The
projection of lunar nodes on the asteroid belt may then be conveniently taken as
modern Rahu. Some mass from this planetary collision could have got ejected as
comets that latter perhaps formed part of Jupiter's family or formed part of Kuiper Belt.
Hence, the Rahu/Ketu analogy is plausible.
Obviously, this Rahu would have Mars and Jupiter along with the traditional rivals,
the Sun and the Moon, as its enemies. Not surprisingly, a number of texts do list
6 Donald W. Patten and Samuel R. Windsor, The Mars-Earth Wars (Seattle: Pacific Meridian Publishing Co., 1996). 7 Velikovsky, Immanuel, Worlds in Collision (Paradigma Ltd. Later Printing edition, 2009).

either Mars or Jupiter or both as the enemies of Rahu, in addition to the Sun and the
Moon.
It is further believed that as a result of this close encounter of Mars with Rahu,
Rahu shattered into numerous fragments now known as asteroids and Mars acquired a
different orbit. This new orbit came perilously close to both Venus and Earth.
Whenever Mars approached the Earth, it led to traumatic events on our planet in
terms of monstrous tidal waves, volcanic eruptions, electromagnetic discharges or
lightning bolts, tilting of earths axis and similar disasters recorded as Acts of God in
Biblical and other ancient texts. Finally, when Mars had an extra close encounter with
both Venus and Earth in 701, BCE, its energy increased sufficiently to allow it to
expand its orbit, which was further rounded out over the course of time because of
perturbations from Jupiter and other planets. The reader is referred to the original text
for a more detailed and in-depth analysis of the subject.
The result of this final fling of Mars was a change in orbital periods of Venus, Earth
(or Sun as seen from Earth), Moon and Mars. It is possible that the Sun and Moon
and other planets of Solar system considered Mars and Jupiter as their enemies during
the catastrophic era because of their role in the disintegration of Rahu and its
subsequent effect on the orbits of other planets.
iv. Another planetary catastrophic scenario has been speculated upon by Immanuel
Velikovsky, in which Venus is supposed to have been ejected out of Jupiter and this
proto-Venus was mainly responsible for wreaking cosmic havoc through its encounters,
first with Earth and then with Mars. The periodicity of these catastrophes has been
assumed to be 52 years, based mainly upon Israelite and Mayan traditions and folklore.
Velikovsky notes that comets do not return at exact periods due to perturbations caused
by larger planets. Thus, it is possible that the propounders of Ashtottari dasha were of
the opinion that Venus was responsible for the catastrophes, however, they observed a
periodicity of 54 years (or 108 years for successive day or nighttime catastrophes) as
discussed by Patten et al rather than 52 or 104 years8. Also, it has been noted in ancient
traditions that Jupiter or its Greek counterpart Zeus, was responsible for orchestrating
the celestial events, which could be related to the ejection of proto-Venus.
Later, when Mars became the cause of catastrophes, its periodicity of approach was
supposed to be around 14 to 16 years, similar to its perihelion period now. Assuming
this was actually 13.5 years on an average, there would be 4 approaches in 54 years and
8 in 108 years. According to Latin historians, when the Roman Empire was founded
8 In fact, the total dasha spans of a great many dasha systems could perhaps be explained from this catastrophe theory by tweaking the catastrophe periodicity a bit. However, this topic will be dealt with separately in another communication.

(around 747, BCE) the movement of Sun was disrupted. Also, the night of
annihilation of Sennacheribs army is speculated to be in 687, BCE, a difference of
about 60 years for day and night-time catastrophes. Also, the cult of Mars was known
to have two festivals of Mars, one in March and another in October, similar to the fly-
bys described by Patten.
v. Comets have been observed since ancient times in India and have been described by
Sage Parashara and others, along with the aftermath of each9. The dreaded comet
Samvartaka is noted to be appearing after a lapse of 108 years after its predecessor
Avarta-ketu. The time elapsed between the appearance of successive comets varies
from about 100 years to 130 years in most of the cases described by Parashara, Vriddha
Garga and others. Assuming that different dasha systems were developed in the wake
of the mayhem caused by different comets, the total dasha span of various dasha
systems may be readily explained from this. The Samvartaka comet in particular
appears to be dreaded in various mythological texts and is even said to be responsible
for reducing the world, possibly through heavy rains or deluge. Particularly, appearing
together with Dhumaketu, it is supposed to wreak havoc on earth. In planetary
catastrophe works, also, two comets or starry bodies have been described as being
observed in the sky with similar descriptions of smoky appearance, copper color etc.
Some of these comets could have brushed close to earth or could have been responsible
for the disintegration of Rahu or could even be proto-Venus or priori-Mars with
cometary tails and appearance as speculated by Velikovsky and Patten.
vi. The importance of sacred number 108 in Hindu literature is well known10
. Right from
108 shri before the names of holy saints to 108 beads in japamala or rosary, the literature
and lifestyle is rife with the mention or occurrence of the number 108.
As believed in Ayurveda, there is a chain of 108 links in body held together by 107
marmas or weak spots.
The distance between the Sun and Earth is of 108 times the Suns diameter and the
distance between the Earth and Moon is 108 times the Moon's diameter. Also, the
diameter of Sun is 108 times the Earth's diameter.
The orbital period of Saturn is 10,885 days, approximately 100 times of 108. In fact, as
postulated in the planetary catastrophe theory, the orbits of all the planets before the

-
present order were in perfect ratio and Saturn, in all probability had an orbital period
of 30 years with 360 days per year. This would mean exactly 10800 days for Saturn's
orbital period.
vii. Assuming a normal man breathes around 15 times in one minute, the total
number of breaths is around 21,600 during the whole day. 108 is half of 216.
viii. Assuming the Moon to take approximately 27 days for one orbit or one day
in one nakshatra made up of 4 padas, one orbit of moon corresponds to 108 padas.
Taking 1 year to be equivalent with Moon's stay in one pada, the total dasha span
comes to 108 years.
2. Conditions Of Applicability
he logic behind the conditions of applicability of Ashtottari dasha system
may also be deduced from the planetary catastrophe hypothesis.
i. Various catastrophes have been shown to have occurred in Asia-Europe at a
regular interval of 54 years or its multiples, either in October during day time or in
March during night time corresponding to the close fly-bys of Mars (i.e. in general,
catastrophes were observed to occur during daytime in Sun's Dakshinayana and during
night-time in the Sun's Uttarayana, respectively). Before birth, these conditions could
be fulfilled by Moon and Sun's ayans could be replaced with Moon's dark and bright
fortnights for daytime and night-time births, respectively.
ii. The ancient orbital periods of Mars and Jupiter were in 1:6 ratio. Thus, the semi-major
axes of their respective elliptical orbits were perpendicular to each other. It has also
been shown that the position of Jupiter was precisely perpendicular to the Earth and
Mars during each and every March case flyby. The roles of Mars and Jupiter after
birth during planetary catastrophe events could be played by the Lord of Ascendant
and Rahu at the epoch of birth, thus making this planetary catastrophe inspired dasha
applicable in the natives chart. As per the conditions of applicability, Rahu should be
either perpendicular or in trine with the Lord of ascendant.
iii. It has been shown that during mega catastrophe events, Jupiter was either in Cancer or
Capricorn and Saturn opposite to it. At the time of Biblical floods it has been shown
that Uranus and Neptune, too, could be together with Saturn in Capricorn leading to
the unprecedented deluge. It has been argued that the orbit of Mars could widen
slightly (but dangerously for Earth) due to the exchange of angular momentum
between planets. Thus, the widening of orbit or the proximity of Mars fly-bys could
depend upon the position of other planets. The condition of Rahu being alone or with
T
-
other planets for taking the starting nakshatra as either Krittika or Ardra could also
allude to this arrangement of other planets.
iv. The fact that these potentially disastrous conditions and ancient orbital periods no
longer exist in modern times could have prompted Maharishi Parashar to recommend
Vimshottari dasha for the general populace, a fact also borne out by the results
obtained by various astrologers (yatha pinde tatha brahmande or As above, so below).
Assuming this to be true, BPHS may safely be dated as being more recent than 701
BCE, as it is generally assumed to be. Ashtottari dasha may be taken to be applicable
only in those charts where the birth conditions mimic the planetary catastrophe
environment as spelt out in the conditions of applicability of this dasha.
3. Dasha sequence
Following observations are in order:
i. During the catastrophic era, the orbits of planet Mars and Venus were much more
elliptical than at present as discussed earlier. As discussed by Velikovsky, after
ejection from Jupiter, the orbit of Venus was quite elongated and possibly stretched
almost up to the Asteroid Belt (maximum distance from Earth could be greater than 1
a.u., where 1 a.u.= Sun-Earth distance) and the orbit of Mars, too, was more elongated
(possibly maximum distance from Earth was greater than 0.61 a.u. and lesser than 1.0
a.u). Then, starting from Saturn, the orbits are in decreasing order of their distance
from Earth (viz. Saturn, Jupiter, Rahu - asteroid, Venus, Sun/Moon, Mars and
Mercury). Sun and Moon are taken as a single unit because of their equal angular
extent as discussed in earlier article.
ii. Again, assuming Mercury to be actually Uranus (Mercury's higher octave) and
considering the possibility that during planetary catastrophe era, Mars actually passed
between the Earth and Moon, the sequence in decreasing order of distance from Earth
becomes Mercury (Uranus), Saturn, Jupiter, Rahu, Venus, Moon(Sun) and Mars.
Finally, although the closest distance of Mars from Earth was lesser than that of
Moon, the farthest distance was more than Mercury's. Considering the brightness and
size of Mercury and the farthest distance of Mars would have led to Mercury being
placed on a lower level in dasha sequence, which would now become Saturn, Jupiter,
Rahu, Venus, Moon(Sun), Mars and Mercury (as Mercury itself).
These observations seem to be more plausible and in line with the earlier cataclysmic
scenario, where the orbits of inner planets crossed one another leading to the jumbling
of dasha sequence. It should be noted that we arrive at the correct sequence with
respect to decreasing order of distance of the planet from Sun (i.e. Saturn, Jupiter,
Rahu - asteroids, Mars, Earth or Sun-Moon, Venus and Mercury). Merely by
-
interchanging the positions of two planets in the dasha sequence of Ashtottari system
(viz. Mars and Venus), the same two planets held responsible for planetary
catastrophism by most of the researchers, further lending substance to our speculation
that planetary catastrophism could be at the root of Ashtottari system.
4. Dasha Periods
In general, the following broad observations may be noted:
i. It may be observed that the dashas of benefic and malefic planets are in alternate
order. Also, starting from the Sun, the dasha periods of malefic planets are increasing
even numbers (viz. 6, 8, 10 and 12 years for Sun, Mars, Saturn and Rahu, respectively).
Similarly, the dasha periods of benefic planets are increasing odd numbers starting
from 15 years for Moon (viz. 15, 17, 19 and 21 years for Moon, Mercury, Jupiter and
Venus, respectively).
This may also be viewed as malefic or benefic planet dasha starting with half of
Jupiter or Saturn ancient orbital periods, respectively, and one Mars ancient period
added for each subsequent malefic or benefic planet dasha. These orbital periods are
approximately the same even today.
ii. In general, the Mahadasha period is seen to correspond consistently with 10 synodic
periods or 10 orbital revolutions of rival planets as defined in earlier article. At the
same time, it is noticed that these periods may also coincide with other major events
associated with other planets.
For Vimshottari dasha, as each planet owns 3 nakshatras with full dasha period
corresponding to each, one revolution of Moon around the Earth corresponds to 3
dasha periods or, 1 dasha period corresponds to 1/3 of the orbital or synodic period.
Thus, some of the planets in Vimshottari dasha were shown to have dasha periods
equal to 1/3 of the orbital or synodic period of their rivals. In Ashtottari dasha,
although each planet owns 3 or 4 nakshatras depending upon whether the planet is
benefic or malefic, respectively, the total dasha period corresponds to the stay of Moon
in all the nakshatras taken together. Thus, one revolution of Moon around the Earth
corresponds to one dasha period for one planet or graha. Correspondingly, the dasha
period for certain planets is seen to be equal to one orbital or synodic period of its rival
graha or, alternatively, 10 times this period as discussed earlier.
iii. As a special case, the planets involved in the Planetary Catastrophe phenomenon (viz.
Earth or Sun-Moon and Mars), have dasha periods equal to half of this period (i.e.
either , or 5 orbital or synodic periods). This could be because of the overlapping of
-
the orbits of these planets during the catastrophic era leading to premature ending of
dasha with one half of the dasha periods being the effective dasha period for these
planets. Consistent with Pattenss hypothesis, Mars is supposed to have travelled
between the Earth and the Moon which could lead to the reduction of Moons
influence on Earth as well as reduction of the effect of other planets on Mars.
Obviously this dasha is concerned only with the catastrophic effects on humans or the
Earth-Moon-Sun system and the planets directly responsible for it. The Dasha system
could also have been originated after the disintegration of Rahu (i.e. after 3000 BCE),
in effect lending the dangerous orbit to Mars as per Patten. Thus, Rahu and other
outer planets are not affected and have their full dasha periods without reduction.
iv. There is also a subtle underlying pattern in the dasha periods of planets where the
theme of one-half the orbital or synodic period is noticeable when Mars or Jupiter is
involved in the dasha period calculation. This is further explored in the observations
on dasha periods of individual planets.
Because of the role played by Jupiter and Mars in the planetary catastrophe events, it
is possible that all the planets in this dasha system consider Jupiter and Mars as their
enemies. It would be interesting to see whether the antar dasha of Jupiter or Mars is,
in general, considered to be malefic for the Maha dashas of all the planets in Ashtottari
dasha system. However, no dashaphal (dasha results) specific to Ashtottari dasha has
come to the author's notice.
Mostly, the same dasha and antar dasha results are taken to be applicable for
Vimshottari as well as other dasha systems.
Although the above assumption of Jupiter and or Mars being a universal rival is not
absolutely necessary for the logic developed here, as generally there are other
observations consistently seen to be supporting the derivation of dasha periods of
planets, the correlation between the orbital periods of Jupiter and Mars with the dasha
periods of planets is nonetheless interesting.
v. Jupiter is usually called the great benefic as it normally deflects most of the meteorites
and comets approaching the Solar system towards itself, thereby protecting other
planets11. However, just once in a while, it may also deflect a meteorite or two towards
one of the other planets assuming the role of a villain for the Solar system. As a
consequence of one such unfortunate incident, Jupiter could have perturbed the orbit
of Rahu or Mars because of its gravity or by deflecting a meteorite towards one of
these, thereby dislodging it from its earlier stable orbit.
11 Similarly, it is possible that Saturn could be considered a malefic in general, because it could have been diverting
meteorites towards the Earth or other planets. The role played by Mars and Rahu as discussed above may complete the trio of malefics.
-
Also, it is known that the magnetosphere of Jupiter is the largest among all the
planets, next only to that of Sun. The magnetosphere of Sun is thus opposed and
shaped by Jupiter's magnetosphere, making the Sun and Jupiter rivals. It is also known
that the Sun moves around its barycentre (centre of mass of solar system) because of
the pull exerted mainly by Jupiter. These could be some of the reasons for the
perceived enmity between the Sun and Jupiter as elaborated later.
It is also believed that the placement of Jupiter with respect to Mars at the time of
Mars fly-bys determines the actual closest approach distance and the extent of damage
done. It has also been noted in ancient mythological literature that Jupiter or its Greek
counterpart Zeus, was responsible for orchestrating the planetary catastrophe events.
vi. On the whole, compared to Vimshottari dasha, the dasha period of benefic planets (72
years) in Ashtottari dasha is much more than the dasha period of malefic planets (36
years). Of course, this assuming that Jupiter is a benefic planet in this system.
However, as discussed earlier, if all the planets consider Jupiter as an enemy or as a
malefic planet, then the dasha period of benefics and malefics planets would be almost
the same (i.e. 53 years for benefic planets and 55 years for malefic planets). The fact
that Jupiter could be an enemy for other planets is also borne out by other observations
on the dasha periods of individual planets as discussed below. Thus, further research
may be required on the role of Jupiter in Ashtottari Dasha system.
Dasha Periods of Each Planet
n view of the discussion in preceding sections, some important observations
regarding the dasha period of each planet are given below:
Sun - 6 years
a. During this period, Venus, one of the bitter enemies of the Sun, completes almost 10
revolutions around the Sun. One revolution of Venus around the Sun takes 0.61 years.
Ten of such revolutions rounded to nearest year would be of 6 years.
b. As mentioned previously, the dasha period of planets affected by the catastrophe
corresponds to one half the orbital or synodic period of its rival or 5 times these
periods. As discussed before, it is possible that all the planets consider Jupiter and
Mars as their enemies in this particular dasha system. 6 years is one half the orbital
period of Jupiter, a possible rival of Sun and other catastrophic event affected planet.
c. Neptune, often considered to be the higher octave of Venus, moves one nakshatra
angular distance (165/28=5.9 or 165/27=6.1 years). It is often observed that planets give
noticeable results during transition from one nakshatra to other or from one sign to
I
-
other as in the case of Sadhesati. The changes of Maha Dashas are similarly a period to
watch out for.
d. As discussed in the article on Vimshottari dasha, the 18 year Saros eclipse cycle was
known during Rig Vedic period and the cycle was further divided into three cycles of 6
year each.
e. The effective period of Sun is said to be an ayan or 6 months (i.e. half of its revolution
period of one year). Correspondingly, if Jupiter can be thought of as taking over the
role of Sun after birth in the Ashtottari system, the dasha period of Sun is one ayan or
one half of Jupiter's revolution period of 12 years (11.86 years).
f. If Jupiter's position in the zodiac at the start of dasha is taken as its Ascendant, then
Jupiter goes to the region called Bhu loka (the earthly plane, from the longitude of the
Descendant to the end of the sign) after 6 years. It shows death and rebirth as this is
also the Mrityu loka or where death occurs, and this is where the dasha ends.
Similarly, planetary catastrophe theory talks about the destruction of planets, deluge
and other nasty events.
g. 6 years is 1/5 of the orbital period of its rival, Saturn (29.4/5 = 5.88 years).
Moon - 15 years
a. 15 years is one half the orbital period of Saturn, who considers Moon as its enemy.
b. Mars, perhaps one of the enemies of Moon (and other planets) in the Catastrophic era,
completes almost exactly 7 synods with the Sun in this period (2.135*7= 14.95 years),
thus aligning with the Sun at its starting position. At the same time, Mars completes 8
orbital revolutions around the Sun in 15 years (1.881*8= 15.048 years).
Mars - 8 years
a. Venus, although neutral with respect to Mars, owns the houses exactly opposite to
those of Mars (The other pairs being Saturn's houses opposite to those of Moon and
Sun, and Mercury's houses being opposite to those of Jupiter's) and is of opposite
polarity to Mars. Also, as discussed earlier, Mars might have just strayed a bit too
close to Venus during the catastrophic era, turning it into an enemy. Now, 8 years is 5
times the synodic period of Venus with Sun (1.6*5).
b. 8 years is also the period during which Venus completes its famous pentagram,
returning to align with the Sun at almost the same point that it started.
c. The Hilda Asteroids, having three heads and retrograde perihelion motion have a
period of 8 years. These could be dubbed as Rahu because of their appearance and
-
motion. Rahu is a rival of Mars.
d. The synodic period of Jupiter and Asteroid Ceres (pre-explosion Rahu?) as per modern
orbital periods is approximately 8 years (11.86*4.6/ (11.86-4.6) = 7.5 years). Assuming
slight changes to these orbits due to planetary catastrophes and even assuming that
Jupiter's orbit remained unchanged after planetary collisions, the modern orbit of
Rahu could have changed marginally from ancient 4.8 years to 4.6 years after
disintegration. Then, the ancient synodic period between Jupiter and Ceres (Rahu?)
would be 8.06 years. If the ancient periods of Jupiter and Ceres are assumed to be 12
years and 4.8 years, respectively, the synodic period would be exactly 8 years.
Mercury - 17 years
a. Mars considers Mercury as its natural enemy. Now, if the definition of synodic period
given in earlier article as that of repeating the same angle between two lines is used,
the Sun-Mars line and the line joining lunar nodes are at the same angle relative to
each other after every 1.708 years. Thus, after every 1.708 years, the Sun-Mars line
again becomes parallel to the nodal line, assuming that initially these two lines were
parallel or coincident. After ten of such similar configurations of Sun and Mars line
with the nodal line or after approximately 17.08 years, these two lines almost coincide
(i.e. Mars and Sun also align closely with actual lunar nodes Rahu and Ketu when seen
from Earth). As is known, Mars and Rahu are enemies as well.
Also, seen from Earth, eclipses are possible if Sun and Moon are positioned on the axis
defined by lunar nodes. When seen from the Sun, such a situation is possible if a line
parallel to the axis of lunar nodes is drawn through the Sun, and Moon and Earth are
present on it. In fact eclipses are possible only when both these lines coincide. This
axis spins around the Sun with retrograde motion and orbital period of 18.6 years. The
nodes Rahu and Ketu could alternatively be defined on this line, say, at points where
this line intersects the orbit of asteroids. Then, the synodic period of Mars with this
Rahu is 1.708 years (1.881*18.6 / (1.881+18.6) = 1.708 years). 17 years corresponds to 10
such synodic periods.
b. 17 years is also almost 8 times the synodic period of Mars with Sun (2.135 * 8 = 17.08)
and at the same time 9 times the orbital period of Mars (1.881 * 9 = 16.93).
c. This period is also equal to the perihelion opposition of Mars or the period after which
Mars is closest to Earth.
d. 17 years is also almost 1/10 of the synodic period of Uranus and Neptune (171.1 years).
Uranus is considered to be the higher octave of Mercury.
e. The Moon is an enemy of Mercury. 17 years is also the interval after which the Moon's
following phase is repeated.
-
Saturn - 10 years
a. This is the time needed by Sun (or the Earth-Moon system), an enemy of Saturn, to
go around the Earth (Sun) 10 times.
b. This is also approximately the time taken by Mars to complete 5 orbits (1.881 * 5 =
9.405). Mars is a rival of Saturn.
c. The orbital period of Mars is supposed to be exactly 2 years during the catastrophic
era. Thus, 10 years corresponds to 5 ancient orbital periods of Mars.
d. The synodic period of Saturn and Jupiter is almost 20 years (11.86*29.4 / (29.4-11.86) =
19.88 years). Assuming Jupiter is one of the enemies of all the planets, 10 years is
approximately one half this synodic period. The ancient synodic period would be
exactly 20 years with 30 years and 12 years as the ancient orbital periods of Saturn and
Jupiter, respectively.
Jupiter - 19 years
a. 19 years is approximately the time taken by Rahu (18.6 years) for making one orbit
around the Earth. Rahu, as discussed earlier, is a rival of Jupiter.
b. Mars, probably another planet considering Jupiter as its enemy, completes 10
revolutions around the Sun during this period. The orbital period of Mars is 1.881
years, very close to 1.9 years. (1.881 * 10 = 18.81 years).
c. This is also the period of Metonic cycle of Moon. As postulated earlier, perhaps Jupiter
is considered to be a villain by the planets because of its role in initiating the
catastrophic era. Moon repeats the same phase and is at the same position in zodiac
after this period corresponding to 235 synodic months. This leads to lunar eclipses
occurring on about the same calendar day and at almost the same time (within a few
hours) separated by 19 years.
Rahu - 12 years
a. 12 years is the orbital period of Jupiter, one of the enemies of Rahu and responsible for
its disintegration during the catastrophic era. As discussed earlier, Jupiter is listed as
an enemy of Rahu in many of the modern texts on astrology too.
Venus - 21 years
a. The synodic period of Mars is 2.135 years. Mars is not a friend of Venus, but it is a
sama (neutral) planet to Venus. However, the houses owned by Mars (1st and 8th) are
-
exactly opposite towards those owned by Venus (2nd and 7th) making these planets of
opposite polarities and rivals as discussed earlier. Also, Mars is an enemy of Venus
because of its dangerous eccentricity during the catastrophic era. 21 years corresponds
to approximately 10 cycles of the synodic period of Mars.
b. The planet Pluto, considered the higher octave of Mars, has a mean motion of
approximately 21 years in one sign (248 / 12 = 20.67 years). Given the long orbital period
and eccentricity of Pluto's orbit, 21 years is a fair estimate for the mean period of stay
in one sign. If we remember that the internal motion of the microcosm directly
affecting us and mirroring the macrocosm need not have the same orbital eccentricity
as the planets in macrocosm, the mean motions may very well be taken for dasha
calculations.
Inferences Drawn From Observations
1. The dasha periods are seen to correspond with either 1 or 10 synodic periods or orbital
revolutions of rival planets, or one half of this period for certain planets involved
closely in the planetary catastrophe hypothesis.
2. A high degree of symmetry is observed in the determination of dasha periods (e.g. the
dasha period of Rahu depends upon Jupiter and that of Jupiter depends upon Rahu).
The other pairs are Venus/Mars and Saturn/Sun-Moon.
3. The dasha periods of all the planets have been observed to be dependent upon the
orbital or synodic periods of either Mars or Jupiter, in some way. It is possible that all
the planets consider Mars and Jupiter as their enemies in this dasha system. This
appears to be a concept where more research is warranted.
4. The dasha period of Sun and Moon together (21 years) is around one half of Jupiter
and Saturn's orbital periods (11.8 + 29.4 = 42.2) and about 10 times the synodic period of
Mars (2.135 * 10 = 21.35). In an interesting parallel, for Vimshottari dasha, as shown in
an earlier article, the combined period of Sun and Moon (16 years) is 1/3 of Rahus and
Saturn's orbital periods and 10 times the synodic period of Venus. There, the theme
was either 1/3 or 10 times, here it is 1/2 or 10 times. Corresponding planets in the two
dashas (viz. Jupiter and Rahu or Mars and Venus) are rivals, with Saturn being
common to both dasha systems.
5. If a year of 360 days is taken, most of the dasha periods remain almost the same.
However, 19 year dasha period of Jupiter corresponding to 6840 days is almost equal to
59 synodic periods of Mercury. Mercury is an enemy of Jupiter. The 10 year dasha
period of Saturn would then correspond to almost exact multiple of lunations of 29.5
days each, with perhaps one intercalary day per 10 years. The orbital period of Saturn
is also 29.8 of such years and one half is closer to 15 years dasha period of Moon.

Similarly, Jupiter's period is 12.03 of such years. Thus, one half of this or equivalent
ayan is 6 years for Sun's period. The period of Mars is 1.9085 of such years and ten
times is 19.085 for Jupiter's period.
t has been shown in this article that the theme developed in the earlier article on
Vimshottari dasha holds in the case of Ashtottari dasha too, thereby reinforcing
our confidence in the observations and inferences noted for each system. It has
been shown that the dasha periods of planets in Ashtottari dasha system, too, may
very well be derived from the orbital properties of rival planets as defined in an earlier
article on Vimshottari dasha. It was consistently observed that the Mahadasha period
of planets is either equal to 10 synodic periods (orbital revolution periods) of their rival
planets or 1 synodic period. It has been speculated that the Ashtottari dasha system
could be more relevant during or inspired from the planetary catastrophic era, and the
conditions of applicability of this dasha system could be evolved from the planetary
conditions existing then. The dasha sequence also serves to strengthen this belief. As
the Ashtottari dasha system is a conditional dasha system, certain planets actively
involved in the catastrophe are shown to have the duration of their dasha period one
half of the normally expected period (i.e. 5 orbital or synodic periods or 1/2 orbital or
synodic period). A high degree of symmetry was also observed in the calculations
leading to pairs of planets with interdependent dasha periods. The planets Jupiter and
Mars have been observed to have some co-relation with the dasha periods of all the
planets. It has been proposed that this could be due to the role played by these two
planets in the planetary catastrophic events, thereby requiring a more thorough
assessment of their dasha and antar dasha results.
It is sincerely hoped that this article will inspire other learned workers in this field to
modify and improve upon this work and extend it to other dasha systems.
