Lord Vishnu is one of the major deities in Hinduism and is considered to be the preserver and protector of the universe. According to Hindu mythology, Lord Vishnu is one of the trinity of supreme gods, along with Lord Brahma, who is the creator, and Lord Shiva, who is the destroyer.
Lord Vishnu is often depicted with a blue complexion and is depicted holding four objects in his hands, which represent his various powers and qualities. These objects are a conch shell, a discus, a mace, and a lotus flower.
Lord Vishnu is also associated with many avatars or incarnations, the most popular of which are Lord Rama and Lord Krishna. The avatars of Lord Vishnu are believed to have been sent to earth to restore the balance of good and evil and to protect the world from destruction.
Worship of Lord Vishnu is widespread in India, and his temples can be found throughout the country. Many Hindu festivals and rituals are also dedicated to Lord Vishnu, including the festival of Diwali, which celebrates the return of Lord Rama from his exile.
