Srirudram, also known as Rudraprasna, is a hymn devoted to lord Shiva. It is part of the Yajur Veda and one of the greatest of the Vedic hymns. Sri Rudram is in two parts. The first part, chapter 16 of the Yajurveda, is known as Namakam because of the repeated use of the word "Namo" in it. The second part, chapter 18 of the Yajurveda, is known as chamakam because of the repeated use of the words "Chame".
Rudram is divided into 11 sections called Anuvakas. In the first Anuvaka, Rudra is asked to turn away his Ghora rupa (fierce appearance) and to please keep his and his followers' weapons at bay. Having been pacified, Rudra is requested to destroy the sins of those for whom it is being chanted.
