Sattras are monastic institutions found primarily in the state of Assam, India. They are centers of the Vaishnavism faith, which worships the deity Lord Krishna. Established by the saint Srimanta Sankardev in the 15th century, Sattras serve as places for spiritual learning, cultural activities, and community gatherings. These institutions play a vital role in preserving the rich traditions of Assamese culture, including music, dance, and art. Sattras are often associated with the performance of Ankian Nat, a traditional form of drama, and host various festivals that attract devotees and tourists alike.
