“Where ardent devotees perform duties pleasing to God, where nine-fold
Bhakti prevails, that supreme place adored by Gods and Vaishnavas is called a
Sattra” - Bhatta Deva.(Quoted in ‘Shankardeva and His Times: Early History of
the Vaishnava Faith and Movement in Assam’ - Dr. Maheswar Neog.)
In Sanskrit literature, the term Sattra implies a sacrifice performed by
an assembly of sages lasting for a year or more. Likewise, the Sattra institution of
Assam resembles to a certain extent, the Buddhist Matha institution of the
medieval period. In the early stages of the Neo-Vaishnavite Movement in Assam,
the word Sattra was used to denote a religious sitting or association where the
Bhagavata was read. In their works on Vaishnava Movements in Assam, two
eminent Assamese scholars and researchers, Dr. Maheswar Neog and Dr.
Satyendra Nath Sarmah respectively, also opine that the term Sattra seems to have
been adopted from the Bhagavata Purana.
