Banyan Tree

On the northern peak of Arunachala a certain banyan tree is seen, at the root of which stays Mahesvara perpetually in the guise of a Siddha.

Its shade is very extensive and is always circular in shape. It is always seen by Devas and human beings overwhelmed with surprise.

It shines splendidly on being served by eight Lingas all round, worshipped by the eight Guardians of the Quarters and stationed in the eight directions.
