Navayana (Devanagari: नवयान, IAST: Navayāna) means "new vehicle" and refers to the re-interpretation of Buddhism by B.R. Ambedkar. Ambedkar was born in a Dalit (untouchable) family during the colonial era of India, studied abroad, became a Dalit leader, and announced in 1935 his intent to convert from Hinduism to Buddhism. Thereafter Ambedkar studied texts of Buddhism, found several of its core beliefs and doctrines such as Four Noble Truths and Anatta as flawed and pessimistic, re-interpreted these into what he called "new vehicle" of Buddhism. This is known as Navayana, also known as Bhimayāna after Ambedkar's first name Bhimrao. Ambedkar held a press conference on October 13 1956, announcing his rejection of Theravada and Mahayana vehicles, as well as of Hinduism. Thereafter, he left Hinduism and adopted Navayana, about six weeks before his death.
In the Dalit Buddhist movement of India, Navayana is considered a new branch of Buddhism, different from the traditionally recognized branches of Theravada, Mahayana and Vajrayana. Navayana rejects practices and precepts such as renouncing monk and monastism, karma, rebirth in afterlife, samsara, meditation, enlightenment and Four Noble Truths considered to be foundational in the Buddhist traditions. It radically re-interprets what Buddhism is, revises the original Buddha teaching to be about class struggle and social equality.
Ambedkar called his version of Buddhism Navayana or Neo-Buddhism. His book, The Buddha and His Dhamma is the holy book of Navayana followers.
Ambedkar was a Dalit leader, influential during the colonial era and post-independence period of India. He was the fourteenth child in an impoverished Maharashtra Dalit family, who studied abroad, returned to India in the 1920s and joined the political movement. His focus was social and political rights of the Dalits. To free his community from religious prejudice, he concluded that they must leave Hinduism and convert to another religion. He considered Islam, Christianity, Sikhism and Buddhism. He chose Buddhism in the form of Navayana.
