As per Sri Pillailogam Jeeyar Swamy in his work "Ramanuja Divya Charithai" it is stated that Sri Asoori Kesava Somayaji, father of Sri Ramanuja, performed Putrakaameshti Yagam at Kairavini the temple pond at Thiruvallikeni, and prayed to Sri Parthasarathy to bless him with a son. Sri Parthasarathy appeared in the dreams of Sri Asoori Kesava Somayaji and promised he will be born as his son to impart teachings of his Gita for the benefit of mankind. "Bhagavad Gita Bhāshya" (a review and commentary on the "Bhagavad Gita"),was later written by Sri Ramanuja. In conformity of the above tradition during the annual festival, unlike other Alwars and Acharyas, Sri Ramanuja has independent processions both in the morning and evening.
