Power of Pilgrims

It is said in the Puranas that the Gods themselves come to Arunachala to watch the progress of the pilgrims giripradakshina and that whoever goes around the Hill with a mind fixed on the Lord, will get the benefit of the Lords Grace to such an extent that the dust kicked up by their feet will serve as an instrument of immortality and when they leave, their feet will thereafter sanctify the roads of their own place.
