Vaishnavism is a religious tradition that centers around the worship of Lord Vishnu and his various avatars like Rama and Krishna. It is one of the oldest and most widespread forms of Hinduism. Vaishnavas believe that Vishnu is the preserver and protector of the universe, and by dedicating their lives to him, they aim to achieve moksha (liberation). The Bhagavad Gita, a dialogue between Lord Krishna and Arjuna, is considered a central text for Vaishnavas. The tradition also emphasizes the importance of bhakti, or devotion, in achieving spiritual progress. Over time, Vaishnavism has shaped Indian culture, influencing art, music, and philosophy.
