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.
Ayyavazhi
Arul Nool, the first Ayyavazhi work in print was released in 1927, followed by the Akilam in 1933, almost a century after it had been written down. As a result, Ayyavazhi abandoned active oral traditions in favor of literary scriptures. Ayyavazhi headquarter reports that Ayyavazhi spread more rapidly after Indian Independence (1940s) and still more rapidly through the 1990s. Many Ayyavazhi-based social welfare organisations were established in the late 20th century. Several alternative versions of Akilam, including some controversial versions, were released during the same period. The Anbukkodimakkal Thirucchabai, a democratic bureau, was established by the religious headquarters in the early 1990s to organize and govern the religion. Organisational conferences are held in various cities in South India including Mumbai, Chennai and Thiruvananthapuram.
