Jananatpurvam pitru Marana yoga
Difinition.-The Sun must be in the 6th, 8th or 12th; lord of the 8th must be in the 9th; lord of the 12th in Lagna and the lord of the 6th in the 5th.
Results.-The subject will be a posthumous child.
Remarks.-Birth of posthumous children is a somewhat rare phenomenon but not an infrequent one. The yoga here defined is a round-about one
involving the Sun, and lords of the 6th, 8th and 12th, and their disposition in certain mutual positions. It occurs to me that in order to produce the
full effects, the entire yoga, and not a part of it, should be present in the horoscope.
