According to his autobiography, in June 1936, after having a vision of Krishna, he had a supernatural encounter with the resurrected Spirit of his guru Sri Yukteswar while in a room at the Regent Hotel in Mumbai. During the experience, in which Yogananda physically grasped and held onto his guru's solid form, Sri Yukteswar explained that he now served as a spiritual guide on a high-astral planet, and expounded truths in deep detail regarding: the astral realm, astral planets and the afterlife; the lifestyles, abilities and varying levels of freedoms of astral beings; the workings of karma; man's various superphysical bodies and how he works through them, and other metaphysical topics. With new wisdom and renewed from the encounter, Yogananda and his two western students left India via ocean liner from Mumbai; staying for several weeks in England, they conducted several yoga classes in London and visited historical sites, before leaving for the US in October 1936.
