Definition - What does Shri Rudram mean?
Shri Rudram is most often described as an ancient Vedic hymn, or stotra, found in the Krishna Yajur Veda. Sometimes referred to as a mantra (albeit a long one), Shri Rudram is sung or recited in homage to Rudra, a Hindu deity associated with, and in some traditions considered, an incarnation of Shiva. Rudra is the god of wind, storms and the hunt.
Shri Rudram is derived from the Sanskrit shri, meaning “radiant” or “auspicious,” and is often used as a title of respect. Rudra means “howling” or “roaring”; hence, Rudra's nickname as the howler or the roaring god.
Yogapedia explains Shri Rudram
Also called Satha Rudreeyam and Rudra Prasnam, the Shri Rudram is divided into two parts:
Each part has 11 sections. The first part represents a prayer for Rudra to morph into a peaceful form and describes the various epithets of Rudra, while the second part praises Rudra and prays for the many blessings he can bestow and wishes he can grant.
Shri Rudram is found in two chapters of the fourth book of Taittiriya Samhita in the Krishna Yajur Veda. Namakam is the fifth chapter and Chamakam is the seventh chapter.
