Lord Vishnu is one of the principal deities in Hinduism, known as the preserver and protector of the universe. He is often depicted with a blue complexion, symbolizing his infinite nature, and holds various objects like a conch shell, discus, and mace. Vishnu is revered for his role in maintaining cosmic order and harmony. To fulfill his duty, Lord Vishnu incarnates in different forms, known as avatars.

Devotees worship Vishnu to seek guidance, protection, and blessings in their lives.
