Anushilan Samiti
Anushilan Samiti (Ōnūshīlōn sōmītī, "lit": body-building society) was a Bengali Indian organisation that existed in the first quarter of the twentieth century, and propounded revolutionary violence as the means for ending British rule in India. The organisation arose from a conglomeration of local youth groups and gyms ("Akhara") in Bengal in 1902. It had two prominent, if somewhat independent, arms in East and West Bengal identified as Dhaka Anushilan Samiti centred in Dhaka (modern day Bangladesh), and the Jugantar group (centred at Calcutta) respectively.
Shanti Ashram
"Shanti Ashram" was founded for the first time by Nigamananda on Akshay Tritiya at Kumilla Durgapur in 1314 B.S. The ashram was shifted to Gendaria in Dhaka in 1318 B.S. "Sri Gouranga Anath Niketan" was founded there on the 26th Agrahayana 1318 B.S. The purpose behind it is to serve the distressed, the grieved, the sick and the poor.
There was a disciple of named "Saruram Kalita" purchased a plot of 80 bighas at "Kumarveti Chapri village" of "Kokilamukh", Jorhat in Sibsagar district after taking money from Nigamananda. The Math was instituted on the land. Nigamananda himself founded the "asan" (seat) of Brahama at "Kokilamukh" near Jorhat on the occasion of Akshay Tritiya on 7th Baisakh 1319 B.S. and named it Shanti Ashram.
Seven self-denying swami disciples (Chidananda, Premananda, Swarupananda, Yogananda, Suddhananda, Bodhananda and Saradananda) were initiated in asceticism by Nigamananda. He named this ashram as "Saraswat Math". It has been called "Assam Bangiya Saraswat Math" since 1325 B.S. Being an ascetic relating to the title of "Saraswati" (tradition name) under the Sringeri Math Nigamananda gives the name to his Math as "Saraswata Matha".
