In a verse, Easwara Swami one day questioned
Immaculate one, kindly tell me the names of the flowing river, the dancing Hara and the Uma in the enduring Tiruchuzhi.
Bhagavan then composed the following answer in verse form:
As it destroys the sins of those who bathe in it, the river flowing through Tiruchuzhi is known as Pavahari. As the Lord is worshipped by the entire world, he is known as Bhumisa. The name of the Devi is Tunaimalai Ammai.
