Anushilan Samiti
By 1902, Calcutta had three secret societies working toward the violent overthrow of British rule in India. One was founded by Calcutta student Satish Chandra Basu with the patronage of Calcutta barrister Pramatha Mitra, another was led by Bengali woman Sarala Devi and the third was founded by Aurobindo Ghosh. Ghosh was one of the strongest proponents of militant Indian nationalism at the time. By 1905 the work of Aurobindo and his brother, Barin, enabled Anushilan Samity to spread throughout Bengal. Nationalist writings and publications by Aurobindo and Barin, including "Bande Mataram" and "Jugantar", had a widespread influence on Bengal youth. The 1905 partition of Bengal stimulated radical nationalist sentiments in Bengal's Bhadralok community, helping Anushilan acquire a support base of educated, politically-conscious and disaffected members of local youth societies. Its program emphasized physical training, training its recruits with daggers and "lathis" (bamboo staffs used as weapons). The Dhaka branch of Anushilan was led by Pulin Behari Das, and branches spread throughout East Bengal and Assam. More than 500 branches were opened in eastern Bengal and Assam, linked by "close and detailed organization" to Pulin's headquarters at Dhaka. It absorbed smaller groups in the province, soon overshadowing its parent organisation in Calcutta. Branches of Dhaka Anushilan emerged in Jessore, Khulna, Faridpur, Rajnagar, Rajendrapur, Mohanpur, Barvali and Bakarganj. Estimates of Dhaka Anushilan Samiti's reach indicate a membership of 15,000 to 20,000. Within two years, Dhaka Anushilan devolved its aims from the Swadeshi to that of political terrorism.
Narendra Dabholkar
Gradually, Dabholkar started focusing on eradication of superstition, and joined the Akhil Bharatiya Andhashraddha Nirmoolan Samiti (ABANS). In 1989, he founded the Maharashtra Andhashraddha Nirmoolan Samiti (MANS, "Committee for Eradication of Superstition in Maharashtra" or "Maharashtra Committee for Eradication of Blind Faith"), and campaigned against superstitions, confronting dubious tantriks and claimed holy men who promised 'miracle cures' for ailments. He criticised the country's "godmen", self-styled Hindu ascetics who claim to perform miracles and have many followers. He was the founding member of "Parivartan", a social action centre located in Satara district, that seeks to "empower marginalised members of the community to lead lives of security, dignity, and prosperity". He was closely associated with the Indian rationalist Sanal Edamaruku. He was the editor of a renowned Marathi weekly "Sadhana", which was founded by Sane Guruji. He also served earlier as a vice-president of the Federation of Indian Rationalist Associations.
