His philosophy strongly rejected dogmas, superstitions and conventions such as the caste system. Sarkar taught spiritual practices for self-development and urged the aspirants to take a strong stand against exploitation and corruption. The motto "Self-realization and service to humanity" became the guiding ideal for thousands of people who were attracted to the universal vision of Ananda Marga.
After a few years, the movement had spread through the states of Bihar and West Bengal. In 1962, P.R. Sarkar initiated the first monk of Ananda Marga. The creation of the order of nuns followed in 1966. Most members of Ananda Marga are lay people, including students, married couples, single adults, etc. All are able to benefit from the spiritual practices taught as well as contribute to the society through one or another of Ananda Marga's programs. The monks and nuns, who have dedicated their lives for social service, serve as full time workers of the mission and are instrumental to Ananda Marga's expansion and existence. In 1963, Sarkar expanded the organization with the Education, Relief, and Welfare Section (ERAWS) and opened the first Ananda Marga schools. As Ananda Marga spread all over India in the Sixties, the scope of Ananda Marga's social service grew to include children's homes, medical clinics, feeding programs and disaster relief teams. AMURT (Ananda Marga Universal Relief Team) was started in 1965 and since then has been an ever-present participant on the disaster relief scene.
By 1970 Ananda Marga had become a global organization with branches in Europe, America, Africa, Asia and Australasia. The seed that was planted in the humble Indian village back in 1955 has today grown into a vibrant global network of men and women whose desire is to serve God by serving humanity, across national, economic or ideological barriers.
Today Ananda Marga has become a world-wide movement with spiritual and social activity centers in different countries of the world. The mission runs schools, medical units, children's homes, rural development projects and meditation and yoga centers, and is a leading global agency for social development and progress with particular emphasis in the third world.
