When did George Harrison convert to Hinduism?

During the filming of the movie Help!, a Hindu devotee presented each Beatle with a book about reincarnation. Harrison's interest in Indian culture expanded to Hinduism. During a pilgrimage to Bombay with his wife, Harrison studied sitar, met several gurus and visited various holy places. In 1968, Harrison traveled to Rishikesh in northern India with the other Beatles to study meditation with the Maharishi Mahesh Yogi. In 1969, he and fellow Beatle John Lennon met A.C. Bhaktivedanta Swami Prabhupada, founder - acharya of the International Society for Krishna Consciousness (ISKCON). Soon after, Harrison embraced the Hare Krishna tradition (particularly japa-yoga chanting with beads), became a lifelong devotee, being associated with it until his death.
