As the temple is in a forest area, there are custodian deities, Kannimar and Karupparayan on the right side of the temple.  Muniappan is the custodian deity on the left side. While Lord Ganapathy graces at the front entrance, Sri Anjaneya graces the devotees from the outer prakara.  The temple has the sanctum sanctorum for the presiding Lord, Artha Mandap, Maha Mandap, a two tier Vimana Tower, Lamp post etc.  The consecration of the temple was last performed in the 2013.

People pray here for removal of obstacles in wedding matters, for child boon, for recovery from severe illness, endless worries and mental depressions.  Parents pray for the girls not attaining puberty the appropriate age.  They also pray for good farm yields, excellence in education, employment opportunities, promotion in jobs and to realize their various ambitions.  They do believe that Lord Swayambu Perumal shall come to their rescue in any hour of need and solve their problems without fail.

The news that Lord Perumal is a swayambu spreading in all directions, the devotees are not limited to natives alone, but many in huge numbers visit the temple from nearby states, Karnataka and Kerala too.  They believe that Lord Perumal would bless them with all prosperity and health and grant a bright life without even a spot of darkness.

There lived about 30 Adivasi families in Irularpathi a century back.  They were shepherds.  One of them was Ranga Moopan.  He used to graze his cows and was vending his milk.  He found that one of the cows gave very little quantity while others were giving more.  He wondered where and how the milk disappears despite good feeding.  He followed the particular cow that was heading to a Karai tree and found that it was pouring its milk on a Swayambu.  Exasperated, he beat the cow and drove it away and also brutally raised his sickle to cut the Swayambu who consumed the milk and left him in a loss.  But his hands and legs began to tremble and eyes darkened.  He fell fainted.  Hearing him crying in panic, the villagers came to his rescue and took him home.  After spilling water on his face, Ranga Moopan opened his eyes and narrated his experience. 

An elderly person Thotti Moopan said that Ranga Moopan offended the Lord, took all the people to the place where the Swayambu existed.  All of them fell at the feet of the Swayambu and sought the pardon of the Lord.  Swayambu Perumal was pleased with their prayers and granted His full Vishnu darshan holding his conch and discus, a darshan even those in the celestial world could not have.  Lord Swayambu Perumal told them that He had come to the place only to grace them and their following generations and assured a prosperous and healthy life and salvation finally.  Lord, after granting the boon disappeared.   The villagers built a small temple then.  Ranga Moopan pledged himself and his heirs to the service of Perumal.
