Dinjoy Satra: The Satra is located at Dinjoy about 5kms north of Chabua Township. Amongst the twelve main devotees of Gopal Atadev, the distinguished devotee Aniruddha Dev founded a Satra first at Bisnubalikakunshi village of North Lakhimpur. Later on this Satra was shifted to Khutiaputa. During this period the Moamoria rebellion took place and this Satra fell into troubled waters. This rebellion took place when Astabhuj Gosain (Priest having eight hands) was the ninth head of this Xatra. After his demise, this religious seat of the Satra remained vacant for about fourteen years. Later on Pitambar Chandra Dev was made the head of the Xatra on the orders of Maharaj Gaurinath Singha. The Satra again fell into deep trouble when during this period there occurred a rebellion once again. Even after the end of the Moamaria rebellion this trouble continued at the time when the Burmese invasion began. After stability returned to the kingdom, Bhaktananda Gosain who had been absconding during the Burmese invasion, came to Barbheti Satra situated in Malowpather. Matibor Senapati, the son of Sarbananda Singha of Tinsukia(Bengmora), with due permission of Purnananda Singh Swargadev, brought Bhktananda Gosain first to Rangagara and then later on to the present site of Dinjan at Chabua and named the Satra thus established as Dinjoy Satra.
