Presiding deity Lord Anantha Padamanabha Swami blesses the devotees from the sanctum sanctorum under the Hemakoota Vimana-tower above the sanctum.  Lord Yoga Narasimiha, Sri Anjaneya and Lord Krishna bless the devotees from the prakara, before the sanctum and behind the sanctum respectively.  The butter applied on Sri Hanuman never melts even during scorching summer nor goes junk.  Temples of Lord Lakshmi Varaha and Lord Srinivasa are on the southern side.

Devotees pray for removal of obstacles in wedding matter, for child boon and for good education.

The presiding deity made of Iluppai wood was destroyed by fire in the year 1686.  The second and the present idol was made with 12,000 Salagrama stones of Vishnu importance with a mixture called Kadu Sarkarai Yoga.  This is a very rare idol which we are worshipping now.  The idol on the Adi Sesha is 18 feet long in a reclining posture, covered fully with gold.

An ascetic Vilwamangalam Swamigal was performing pujas to Lord Narayana each day with flowers etc.  A little boy was causing all troubles to Swamigal by scattering the puja materials and even urinating nearby.  It is said that Lord played in the guise of the little boy to test the tolerance level of Swamigal.  When his mischief reached a stage, Swamigal pushed the boy Unni Kannan-little boy in anger.  Lord Kannan appeared before him and said that true bhakti and renunciation required total tolerance and that He so behaved to test him.  He also told the Swamigal that if he desired to see him again, he (swamigal) had to come to Ananthan Kadu.  Lord disappeared then.

Swamigal began to discover Ananthan Kadu but could not.  He sat under a tree much tired on a scorching sunny day.  He saw a peasant couple nearby quarrelling.

The husband shouted that if she was behaving like that, he would kill her and throw her in the Ananthan Kadu.  Swamigal was happy, approached the husband, made peace among them and asked him to show the place.  The husband showed Swamigal Ananthan Kadu.  It was a rough path covered by wild bushes with thorns. Determined, Swamigal found at last Lord with Sridevi and Bhoodevi on Adiseha in the reclining posture and worshipped Him.  Lord further tested the Swamigal to get Him something to eat as He was hungry.  Swamigal gave him unriped mango found in the jungle with salt.  Swamigal informed the king of Travancore about his finding.  The king took Brahmin priests from eight mutts and reached the place.  Though Lord was not there as described by the Swamigal, the king in good faith, built a temple, installed Lord on Adisesha and named Him Anantha Padmanabha Swami.
