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.
Sunder Singh Lyallpuri
In the wake of Hindu-Muslim riots of 1924, Mahatma Gandhi and other national leaders like Maulana Mohammad Ali and Dr M. A. Anusari called a national "Ekta Samelan" at Delhi in 1924 which continued for several days. It concentrated mainly on national unity, mutual trust, love and brotherhood. At the end a Central National Panchayat was constituted which was authorised to recruit further members and expand it to the grass roots. With Mahatma Gandhi as its chairman and Convener, the National Panchayat included, among others, Lala Lajpat Rai, G. K. Nariman, Master Sunder Singh Lyallpuri, Dr S. K. Datta and Hakim Ajmal Khan. In the following years, Master Lyallpuri organised or else participated in several seminars or "Ekta Samelans" for the promotion of mutual love, trust and brotherhood among the Hindus, Muslims, Christians, and the Sikhs. Lyallpuri also remained a member of All India Congress Committee.
