Now let us discuss, the
unique feature of Vedic Astrology i.e. the Dasa System of planets and its
utility in predictions. A good grasp of Vedic Astrology is essential to make
full use of the effects of a Dasa while making predictive analysis. There are
different kinds of Dasas pertaining to the various Planets. Dasas are planetary
periods and sub-periods that rule very precisely defined periods of one’s life
in respective Dasas.
The Dasas are of various
kinds. Amongst them Vimsottari is the most appropriate for the general
population.
But the other Dasas,
followed in special cases, are Astottari, Shodsottari, Dwadasottari,
Panchottari, Shatabdika, Chaturashiti-sama, Dwisaptati-sama, Shashtihayani, and
Shattrishant-sama Dasa.
Our ancients have
described these different kinds of Dasas, based on Nakshatras. Some Maharishis
have made a mention of Kala and Chakra Dasa, but they have recognized the
Kalachakra Dasa, as supreme.
1.
The other kinds of Dasas, propagated by the Sages, are Char, Sthir, Kendra,
Karaka, and Brahmagraha. Apart from these the other Dasas are Manduook, Shoola,
Yogardha, Driga, Trikona, and Rashi.
2.
Some different form of Dasas is also prevalent such as Panchswara, Yogini,
Pinda, Naisargie, Ashtavarga, Sandhya, Pachaka, and Tara Dasa etc.
3.
But all these Dasas are not in common usage.
Vimsottari
Dasda
The Vimsottari Dasa is
considered to be the most appropriate and the best of all Dasas.
In Kali Yuga the natural
lifespan of a human being is generally taken, as 120 years, and while
calculating the Life span the months are taken of 30 days and the year consists
of 12 months.
The year of 360 days
adopted in Vimsottari Dasa of Hindu Astrology is not considered correct and now
a day’s astrologer recommends the use of English Calendar year of 365 days.
This theory is against the spirit, practice and rationale of Vedic Astrology.
Since the Astrology was
prevalent in India much earlier then the birth of the Gregorian English
Calendar which is only 2012 years old now. According to Mahabharata, in Virat
Parva, Chapter, when Arjuna revealed his identity after the completion of 18
year’s exile, Duryodhana raised a technical objection that he had not completed
full 13 years, basing his calculation on the Solar year of 365 ¼ days. But
Bheeshma over ruled the objection, saying that Arjuna has completed full 13
years as per lunar year of 360 days. It clearly shows that Hindu Shastras
recognized only Savana year of 360 days for civil and legal purpose. Further,
the zodiac is divided into 360 degrees as per Savana year of 360 days. By Savana day is meant, the period from one
rising of the Sun to the next rising. It is sixty ghatis or 24 hrs. And 360
such day make one Savana year. Savana time / year is the standard time
according to which astrological calculations are made in Vedic Astrology.
All those who are using
the Lahiri Ephemeris, probably have not been observant to take the notice of
the “N.B.: The months of Dasas shown in this Ephemeris are of 30 days each and
the year is of 360 days”, given at the end of Vimsottari Dasa tables.
If the results of Dasa,
Sub-periods differ among astrologers, it is due to various values of Ayanamsa,
adopted by astrologers according to their pet theories. The Chitra-Paksha
Ayanamsa gives very good results, when the Moon value is taken with parallax,
since the Moon is the nearest to Earth and most fast moving too.
The old Panchang’s, some
of them were calculated with Moon parallax taken in to account. The value of
Moon with parallax vary due to speed of Moon, which changes from 11 deg 30 min
to 15 deg 30 min, the parallax value is 53.32 min for the least speed and 61.91
min for the maximum value, for the middle speed of Moon 13 deg 30 min the
parallax value will be 57.77 min.
(It is a common knowledge,
that to take an aim, to shot with any weapon, we have to close one eye; the
similar theory is to be applied for Moon value also since Moon is closer to
Earth, not for distant Planets.)
