The Nagvasuki Temple, located on the banks of the Ganga in Prayagraj, is dedicated to the King of Snakes. While Triveni Sangam is primary for most rites, this temple is particularly significant if Nag Bali needs to be performed alongside Narayan Bali for removing Sarpa Dosha (curse related to snakes) or Pitru Dosha connected to snakes. Some puja services conduct rituals here.
