According to the legend, this sacred spring was created by God Indra during his battle with Mayadanawa, the evil. The nearby river has been poisoned by this evil and made hundreds of Indris troops sick. God Indra pierced the earth and creates a fountain of immortality to recover his troops.
In the temple complex, you can see the statue of God Indra, very beautiful actually.
