Part 1

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.)
