Dear Consulters, Subscribers and Readers,
Dashas are crucial in depicting the changing trajectory of Karma in the Vedic horoscope. In other words, the same natal horoscope which continues as a constant throughout life, from birth till death, reveals different shades of Karma, largely owing to the operation of the Dashas in life.
I have written earlier, and many of you know from personal experience, that various Dasha systems have been used in individual horoscopes depending on the nature of the astrological investigation, as well as the configurations obtaining in the horoscope.
Some of these include the Narayana Dasha (Padakrama Dasha), an efficacious system of the classics, to interpret the more fated and deterministic contours of the Vedic horoscope. Likewise, the conditional Nakshatra Dashas, such as the Dwisaptati Sama Dasha, Ashtottari Dasha, Dwadashottari Dasha, Shastihayani Dasha, Chaturasheetika Dasha, and so on, have been used, and written of, at various points in time earlier.
Even so, the classical literature is clear that it is the Vimshottari Dasha which is the chief amongst all the Dashas. I have recently written more on the subject given the overarching status of the Vimshottari and the paper under reference delves into the various kinds of Vimshottari Dasha which are to be used depending on the Yogas in the charts. Also, the manner of Judgment of the Dasha, through its Mahadasha and Antardasha is dealt with.
Continuing the theme of traversing ever higher trajectories of Vedic astrology through personal analysis of individual horoscopes, these rarified dicta pertaining to Vimshottari are both being used in the said higher and advanced analysis as well as written in the form of specific advisory on Dasha interpretation.
