Explanation:

 ·In the late fifteenth century, Shankaradeva emerged as one of the leading proponents of Vaishnavism in Assam. His teachings, often known as the Bhagavati dharma because they were based on the Bhagavad Gita and the Bhagavata Purana, focused on absolute surrender to the supreme deity, in this case Vishnu. He emphasised the need for naam kirtan, recitation of the names of the lord in sat sanga or congregations of pious devotees. He also encouraged the establishment of satra or monasteries for the transmission of spiritual knowledge, and naam ghar or prayer halls. Many of these institutions and practices continue to flourish in the region. His major compositions include the Kirtana-ghosha.
