It is one of the most sacred and powerful Vedic hymns and is recited in poojas and homam by Vedic pundits for all round benefits.
The second part known as Chamakam (because of repeated use of word “Chame”) is found in the seventh chapter. The first part known as Namakam (because of the repeated use of word “Namo” in it) is found in the Krishna Yajurveda, Taittariya Samhita in the fourth chapter. Sri Rudram, also known as Rudraprasna, is a hymn devoted to lord Shiva.
