It is believed that in order to lead a normal, happy, smooth life, we need the blessings of our forefathers (Pitru Devatas). Our Pitru Devatas are in the form of serpents. The Kalyan Sarpam is installed under Guru Vriksham, behind Gurustanam.
The Kalyana Sarpam with Bala Mukunda (Krishna) in the center is installed facing the east, blessing all with healthy family life and progeny. Offering prayers to this form is equivalent to praying in Sri Kalahasthi where people go to do Sarpa Prathishta for relief from Rahu-Ketu Dosham or pitru-dosham.
Abhishekam: Weekly Abhishekam is performed here every Sunday. Special Abhishekam is performed on Naga Panchami day in the month of Sravana and Naga Chathurthi in the month of Karthika.
