Arya Samaj is a Hindu reform movement founded in India by Swami Dayananda in 1875. He was a sannyasi (renouncer) who believed in the infallible authority of the Vedas. Dayananda advocated the doctrine of karma and reincarnation, and emphasized the ideals of brahmacharya (chastity) and sanyasa (renunciation). There are approximately 3-4 million followers of Arya Samaj worldwide.
