Madhabdev (1489–1596), also known as Mahapurush, is one of the most popular Vaishnava Saints in Assam. Madhabdev was an important preceptor of the Ekasara ma Dharma, famous for his loyalty to his guru, Sri Sri Srimanta Sankardev as well as his artistic brilliance. 

Initially a Sakta worshipper, he was converted to Ekasara Dharma by Sri Sri Sankardev and became his most prominent disciple. He became the religious as well as the artistic successor of Sri Sri Sankardev after the latter’s death in 1568. 

Srimanta Sankardev preferred Madhabdev over his two sons to carry the Vaishnavite movement forward, and Madhabdev repaid this faith in his faith by carrying forward his guru’s legacy and established several satras (monasteries). 

He is known particularly for his book of hymns, the am Ghosha, as well as a large selection of Borgeets. The Borgeet written by both Sankardev And Madhabdev is known as the soul song of Assam. The Ankia Nat and Jumura are some of the first Indian cultural dramas, written before Shakespeare wrote Hamlet. 

The Saint passed in 1596.  

In 1528, Madhavdeva established the famous Dhekiakhowa Bornaamghar, a naamghar (prayer house)  in Jorhat district, Assam, India. He kindled an earthen lamp there, which has been continuously burning ever since and a strong contender for the longest continuously lit lamp in the world.
