Brahmacharya is an ancient Sanskrit term that identifies one of the major yamasor norms of restraint for spiritual aspirants cited in the Hindu scriptures. It literally means God-conduct, but is normally applied to the vow or practice of celibacy. Gandhi, while still in South Africa in 1906, decided to take this vow. He understood there was no deeper source of power in the human psyche than the sexual drive and knew that he would need all of his power focused to overcome the tremendous challenges he faced in rousing an entire nation to nonviolent resistance. Mastering it, which took him many years, proved to be a source of “a joy and a sense of wonder in the power of nature that [he] had no power to describe.”
