Papanasini is a spring fed stream that originates in the Brahmagiri Hills, which later joins the River Kalindi. Located about a kilometer from the Thirunelli Vishnu Temple, devotees believe that the cool waters have the ability to wipe away a lifetime of sins.
It is believed that the River Ganga and the River Saraswathi join in Papanasini, making its waters (the name Papanasini means “washes away all sins”) all the more holy.
