Narayana

Narayana (Sanskrit: नारायण, IAST: Nārāyaṇa) is known as one who is in yogic slumber on the celestial waters, referring to Lord Maha Vishnu. He is also known as the "Purusha" and is considered Supreme being in Vaishnavism. According to the Bhagavat Gita, he is also the "Guru of the Universe". The Bhagavata Purana declares Narayana as the Supreme Personality Godhead who engages in the creation of 14 worlds within the universe as Brahma when he deliberately accepts rajas guna, himself sustains, maintains and preserves the universe as Vishnu by accepting sattva guna. Narayana himself annihilates the universe at the end of maha-kalpa as Kalagni Rudra when he accepts tamas guna. According to the Bhagavata Purana, Narayana Sukta, and Narayana Upanishad from the Vedas, he is the ultimate soul. According to Madhvacharya, Narayana is one of the five Vyuhas of Vishnu, which are cosmic emanations of God in contrast to his incarnate avatars. Bryant, Edwin F., Krishna: a Sourcebook. p.359 "Madhvacharya separates Vishnu's manifestations into two groups: Vishnu's vyuhas (emanations) and His avataras (incarnations). The Vyuhas have their basis in the Pancharatras, a sectarian text that was accepted as authoritative by both the Vishishtadvaita and Dvaita schools of Vedanta. They are mechanisms by which the universe is ordered, was created, and evolves. According to Madhvacharya, Vishnu has five vyuhas, named Narayana, Vasudeva, Sankarshana, Pradyumna and Aniruddha, which evolve one after the other in the development of the universe.
