You must do the Pind Daan process through Karnataka Sevashram situate near Vishnupad Temple. They will assign a priest to you or your group. The charge is reasonable. Otherwise, you may be in the hand of local Pandas and loose quite a bit of money. The places (you have to visit three places by car or auto) where you are supposed to do the rituals are dirty though sweepers are there. They do not keep the place clean.
