Sri Rudram called also as Satha Rudreeyam or Rudra Prasnam occurs in Krishna Yjur Veda in the Taithirieeya Samhitha. It has two parts, Namakam and Chamakam each with eleven sections. Namakam is a prayer to Rudra to forget about his avenging fierce, fearful and horrendous form and turn himself into a peaceful form and do good to us. Listening and chanting of this Chamakam bestows peace and bliss.
