Vishnu is seen as the divine arbitrator, who protects justice and moral order by interceding in all disagreements, whether they involve humans or gods. He is known for his patience and his gentle, merciful nature. Vishnu is associated with light - especially the sun.
In almost all Hindu denominations, Vishnu is either worshipped directly or in the form of one of his 10 avatars. The most famous of these avatars are Rama (the seventh) and Krishna (the eighth). Vishnu's wife and active energy is Lakshmi, the Hindu goddess of wealth, fortune and prosperity.
Vishnu is accepted as the main deity and Supreme Being by followers of Vaishnavism, and is also called Vasudeva, Hari, Kesava, Purusottama and Narayana. He is the god of time, space, life and joy. He brings great bliss to his devotees and the world. Vishnu is also the god of Karma yogis, the unselfish servants.
In yoga practice, sleeping Vishnu pose is performed by laying down on one side of the body, propped up on the elbow. Then the top leg is extended upwards with the arm as in reclining hand-to-big-toe pose.
