The Tolappar
tradition is followed by Sri Ahobila Mutt and Thengalai Sri Vaishnavas. It is named after Sri Vaidika Sarvabhauma
Swami, also known as Kidambi Tholappar, who wrote a detailed text establishing
the reasoning behind his tradition. He was a disciple of the founding Jiyar
Swami of Sri Ahobila Mutt.
Observation
1) Only the
solar month is taken into account. So it must be in Simha (Avani) Masam, which
is mid-August to mid-September.
2) The target date in this month is Krishna-Ashtami (8th day of the waning phase of the moon) in conjunction with Rohini. However, on that day, not even a tiny bit of Saptami should exist post-sunrise, nor should there be any Krttika nakshatra.
3) If there is
no pure Ashtami-Rohini conjunction as described in (2), Navami-Rohini is the
next preferred conjunction, with once again a pure Rohini mandatory.
4) If (3) is not
possible, Mrigashira nakshatra combined with Navami Or Dashami is the next
preferred choice.
5) If this observance of Sri Jayanti does not fall on Ashtami, the Ashtami is treated as any other day and requires no special observance.
