About the Shrine:
The shrine is located inside the hill temple, southwest of the sanctum. They say no pilgrim should leave Palani without attending the shrine of Bhogar. It is believed that there is an underground passage here that goes straight to the foot of the main deity, Lord Murugan. Actually Bhogar himself constructed this and went into Nirvigalpa Samadhi here. He is last seen by his disciples at this entrance.
In the shrine is present the idol of Bhuvaneswari Amman and a Shiva lingam made of Maragatha stone (when you visit, ask the priest specifically to show them) worshipped by Bogar. Below these deities is the underground passage where Bogar went into samadhi. Now this has been covered completely without any indication of such a passage. They also say that those who have not been blessed with a child, after they pray coming to this shrine will be blessed with a child.
