Krishnaguru Sewashram, Nasatra is a 500 year old satra. Manohardev, the ardent disciple of Damodardev established the satra. Mahabaishnab Manohardeva around 500 years from now set up a satra on the bank of Suvarnakur, the creation of which is shrouded with supernatural stories. This satra was named as Nasatra and it is around 16 miles away from Barpeta. Divine powers of this satra spread far and near within a very short time. After the demise of Manohardeva, his successors continued to run the satra. On the other hand, the area surrounding Suvarnakur, was covered with thick jungles and it became a habitation of ferocious tigers and poisonous snakes.
Continuing with the tradition of forefathers, one of the ardent devotees Sant Rabidev took up the responsibility of running the Nasatra Dham. In his days also, supernatural deeds of Parameswar Narayana were revealed at Nasatra Dham. To rescue the sinful persons of Kaliyug, Param Purush Narayana incarnated as Krishnaguru on the Ashtami Thithi in the month of Jaistha (the second month of the Indian Calendar) in the year 1934. Since his childhood, Krishnaguru Prabhu started showing his divine powers. He brought about reforms in Sanatana Dharma which was polluted and, after necessary reforms; he has shown the right path of EKA SARANA. Thereby, he has freed the society of superstitions and got involved in other activities aiming at the welfare of the society.
The main aim of Paramguru Krishnaguru Iswar is to establish a society which is spiritually oriented so that with the foundation of such a society, global peace can be ensured. It will be a society where there will be no discrimination on the basis of caste, creed, religion and community. In the year 1974 and in the month of Agrahayan (the eighth month of the Assamese Calendar) on Ras Purnima day when he attained 40 years, Paramguru Krishnaguru Iswar set up Krishnaguru Sewashram at Nasatra which, at that time, was covered with thick jungles frequented by ferocious tigers. From that day onwards, Krishnaguru Mahaprabhu preached Krishnaguru Eknam among the people belonging to various religious faiths. Through the bhaktas, Krishnaguru nam and the divine powers of Krishnaguru Prabhu Iswar spread far and wide and in different parts of the world. Saintly people of various parts of the world came to know about the incarnation of Paramguru Krishnaguru Iswar and his supernatural powers. They have come, all the way, to Krishnaguru Sewashram and after initiation from Krishnaguru Mahaprabhu in Krishnaguru Eknam, they went back and are now implementing the ideals of Paramguru Krishnaguru Prabhu. As a result, within last 35 years, Krishnaguru Sakha Sewashrams have been set up in West Bengal, Bihar, Uttar Pradesh, Rajasthan, Delhi, Orissa, Arunachal Pradesh, Meghalaya, Manipur, Tripura apart from Assam. Steps have now been taken to set up Krishnaguru Sewashram outside the country. At present, there are altogether 90 branches of Krishnaguru Sewashram inside and outside the country.
