Ananda Marga (P.R. Sarkar)

Ananda Marga ("Path of Bliss") was founded in Jamalpur, Bihar, in 1955 by Prabhat Ranjan Sarkar (known to followers as Shrii Shrii Anandamurti), who combined Tantric yoga and meditation practice with a socio-economic doctrine he called PROUT (Progressive Utilization Theory). The organisation is structured around a monastic order of acharyas who take vows of lifelong service, alongside a much larger lay membership practising daily meditation and yoga under Sarkar's prescribed asanas and mudras.

The movement's gravest documented controversies date to the 1970s–80s and involve violence on both sides of the organisation. In 1971 Sarkar was imprisoned in India on charges of ordering the murder of five former Ananda Marga members, and the organisation was banned with its leaders arrested; in 1973 Sarkar was allegedly poisoned by a prison doctor and began a hunger strike demanding investigation that ran five years and four months. He was released and cleared of all charges on 2 August 1978 after the allegations were found to rest on fabricated evidence. Separately, Ananda Marga members were convicted in Australia over the 13 February 1978 Sydney Hilton Hotel bombing, which killed three people during a Commonwealth summit; those convictions rested substantially on a police informant's testimony, were controversial from the start, and led to release by 1985, before a 1989 confession by former member Evan Pederick reopened the case specifically on the Hilton charge (the earlier 1985 release concerned a separate, related conspiracy conviction, not the bombing itself) — Pederick pleaded guilty, and alleged organiser Tim Anderson was convicted of the bombing itself in October 1989 and sentenced to 14 years; in June 1991 the New South Wales Court of Criminal Appeal quashed that conviction and entered a judgment of acquittal — not merely ordering a retrial — amid long-running allegations that Australian security services were themselves implicated in the bombing. Ananda Marga members have also been victims: in April 1982 sixteen monks and a nun were killed and burned at Bijon Setu, West Bengal, in an attack for which no one has ever been convicted despite a 2012 judicial commission.

Since the 1980s, mainstream Ananda Marga has operated as a large, openly registered global movement running schools, disaster relief, and humanitarian work (Ananda Marga Universal Relief Team) across dozens of countries, with no comparable violent incidents reported in recent decades. The historical 1970s–80s episodes above — not the movement's current humanitarian profile — are what anchor this entry's score.
