and several of his disciples, who reported meeting him between 1861 and 1935. Some of these meetings were described by Paramahansa Yogananda in his 1946 book "Autobiography of a Yogi", including a report of Yogananda's own meeting with the yogi. Another account was given by Sri Yukteswar Giri in his 1894 book "The Holy Science". According to Sri M's autobiography (Apprenticed to a Himalayan Master), Babaji was Lord Shiva. In the second last chapter of his book, he mentions Babaji changing his form to that of Lord Shiva. All of these accounts, along with additional reported meetings, are described in various biographies. According to Yogananda's autobiography, Babaji has resided for at least hundreds of years in the remote Himalayan regions of India, seen in person by only a small number of disciples and others.
