In Hindu beliefs, Vishnu is considered the preserver of the universe. He plays a key role in maintaining cosmic order and harmony, intervening whenever chaos arises. Rejuvenating creation through various avatars, such as Rama and Krsna, Vishnu embodies the principles of compassion, protection, and righteousness. His significance lies in ensuring the balance of dharma (moral order) and supporting the cycle of creation, preservation, and dissolution, which are essential themes in Hindu cosmology.
