 NarYana is the only non changing one all else changes.. change is the only constant.

Changing days nights people places seasons everything changes. Time too.

As per texts like the Vishnu Purana, Bhagavata Purana, Garuda Purana, and the Padma Purana, Narayana is Vishnu himself who incarnates in various avatars.

According to the Bhagavad Gita, he is also the "Guru of the Universe". The Bhagavata Purana declares Narayana as the Supreme Personality of Godhead who engages in the creation of 14 worlds within the universe Brahma who is Deity of 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 who is presiding deity of tamas-guna.

According to the Bhagavata Purana, Purusha Sukta, 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. Madhvacharya separates Vishnu's manifestations into two groups: Vishnu's vyuhas (emanations) and His avataras (incarnations).[7] 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. Narayana possesses the chatur-vyuha aspects of Vasudeva, Sankarshana, Pradyumna, and Aniruddha, who evolve one after the other in the development of the universe.
