History of the Anushilan Samiti
Around 1902, Aurobindo Ghosh arranged for Bannerjee to return to Calcutta to begin organisational work, where he began a gymnasium and a youth society. It was at this time that Bannerjee came in touch with Vibhuti Bhushan Bhattacharya, Sarala Devi Ghoshal and Pramathanath Mitra. In Calcutta, a few clubs and societies were still active at the time. Most notable was a gymnasium in Ballygunge Circular Road run by Sarala Devi herself, a second was an organisation named "Anushilan Samiti" founded by Satish Chandra Basu with the patronage of Pramathanath Mitra. A third one was a youth club called "Attōnnōti Samiti" (Self-improvement society) in central Calcutta.
Anushilan Samiti
The organisation's political views were expressed in the journal "Jugantar", founded in March 1906 by Abhinash Bhattacharya, Barindra, Bhupendranath Dutt and Debabrata Basu. It soon became an organ for the radical views of Aurobindo and Anushilan leaders, and lent the name "Jugantar party" to the Calcutta group of Anushilan. Early leaders were Rash Behari Bose, Jatindranath Mukherjee and Jadugopal Mukherjee. Similar messages of violent nationalism were also finding their way to the public in Aurobindo's works in journals such as "Sandhya", "Navashakti" and "Bande Mataram".
