Pancharatra (IAST: Pāñcarātra) was a religious movement in Hinduism that originated in late 1st millennium BCE around the ideas of Narayana and the various avatars of Vishnu as their central deities. The movement later merged with the ancient Bhagavata tradition and contributed to the development of Vaishnavism. The Pancharatra movement created numerous literary treatises in Sanskrit called the Pancharatra Samhitas, and these have been influential Agamic texts within the theistic Vaishnava movements.
