Which Dasha should i use for making prediction - Vimshottari Dasha or Ashtottari Dasha ?
Parasara has advised the use of Ashtottari Dasa by saying that,
(1) If Rahu is placed in a quadrant (Kendra) or trine(Triknona) from the Lord of Ascendant then the use of Ashtottari dasha is advisable.
(2) If birth is at daytime in Krishna Paksha[8] or at nighttime in Sukla Paksha[9], the use of Ashtottari dasa is advisable.
If in birth horoscope condition (1) or (2) is applicable, then use Ashtottari Dasha, else use Vimshottari Dasha.
