Moolamurthy gives darshan with eight hands (Ashtabuja) and Eight aayudhas(Weapons) and hence the name Ashatabujakaram. On the right hand are Chakra, Knife, Pushpa and Arrow and on the left are Shanka, Bow, Gada(Mace) and Khadga. Sarpa which came to kill Nrisimha saw Ashtabujanathan and surrendered to Vishnu. As per the orders by Vishnu, Shiva (Serpent) guards the yagna sala to this day in the form of Sarabesan. The Lord came at the call of Aadimoola and saved the Elephant (Gajendra) who was caught by Crocodile while plucking Lotus flowers for the Lord .
This place is about a km from Kanchi Varadaraja temple.
