There are sannadhis for Govindaraja Perumal in sitting posture and
Ranganatha in sayana in which there is a rare idol of Ashthabuja
Nrisimha with one hand blessing Prahlada and the other in Abhayahastha
and the rest destroying Hiranyakasipu. Sthalapuranam says that this
temple came in to being when the Lord gave darshan to Dhruva. The
Nagaraja had darshan (Pratyaksha) of the Lord hence the name Nagai.
