from Yogis, Destiny, and the Wheel of Time, - ch. 4
In later years, I worked on nearly five hundred horoscopes to find out the time for spiritual initiation. Not those 'herds,' who led like sheep into a camp for collective initiation, but for individual initiation. I chose the best of such gurus and their disciples for my research. The findings are the following:
Vimshottari Dasha (Parashari system)
The mahadasha will generally be of a benefic, or the 5th or 9th lord in the birth horoscope. Part of this will be repeated in the Vimshamsha horoscope (20th divisional chart) also.
Chara Dasha (Jaimini system)
The rashi dasha (sign dasha) will be the 5th or 9th house from the lagna, or alternatively, the dasha containing the putrakaraka (planet with the 5th highest degrees in any sign) or with the putrakaraka in the 5th house from the rashi dasha. Part of this will be repeated in the Vimshamsha horoscope.
In transit, Jupiter will be aspecting natal Ketu, or will be transiting on it, or will be in the 5th or 9th house. Saturn should be aspecting the birth lagna or the lagna lord, but not Ketu. Saturn's aspect on the natal Moon is excellent (for spiritual initiation).
