Significance of Mahanyasapurvaka Rudrabhishekam: Mahath means great (like mahatyam). Nyasam is purification. With these, Mahanyasam is said to be a form of purification. The act of mahanyasam purifies mind, body and soul. In all Mahanyasa purvaka Rudrabhishekam is a special pooja to Lord Siva chanting along with Rudram. An orthodox person who performs Sandhya Vandanam knows Anganyasam and Karanyasam. Like those, Mahanyasam is also a prakriya in pooja. Mahanyasam is said to be done before chanting Rudram. It is given in Bruhath Parasara Smruti.
