When the Sun Shines tells the story of how Hare Krishna came to Britain in the 1960s. It is a touching and personal account of innocence and spiritual adventure at the dawn of the Age of Aquarius. The story begins in San Francisco where the founder of the Hare Krishna Movement, Bhaktivedanta Swami Prabhupada, on a one—man mission from India, gathers young people around him and teaches them about Krishna. A group of Prabhupada's American disciples leave for London, the centre of sixties music and pop culture. There they gain national attention by chanting Hare Krishna and befriending the Beatles. In 1969 Prabhupada arrives in England and stays with John Lennon at Tittenhurst Park, where he lives for three months with his disciples and personally teaches George Harrison.
