Note: This Sirah presenting Astaksara-mantra or Thirumantram as the conclusion of Samaveda. The mantra was actually the sound representation of the deity. There is no different between Astaksara-mantra and The Supreme Personality of Godhead Narayana Himself. One who attained realization on Astaksara-mantra, directly experience the Divine Being of Sriman Narayana Himself. He totally immersed in The Lord’s nama-rupa-guna-lila, His Holy Name, Divine Form, Qualities, and Pastimes. This reminds us with Peyazhvar’s Mundram Thiruvanthadi and also Nammazhvar’s Thiruvaymozhi.
