Shangri-La is a fictional place described in the 1933 novel Lost Horizon by British author James Hilton. Hilton describes Shangri-La as a mystical, harmonious valley, gently guided from a lamasery, enclosed in the western end of the Kunlun Mountains. Shangri-La has become synonymous with any earthly paradise, and particularly a mythical Himalayan utopia – a permanently happy land, isolated from the outside world. In the novel Lost Horizon, the people who live at Shangri-La are almost immortal, living years beyond the normal lifespan and only very slowly aging in appearance. The word also evokes the imagery of exoticism of the Orient. In the ancient Tibetan scriptures, existence of seven such places is mentioned as Nghe-Beyul Khembalung. Khembalung is one of several beyuls ("hidden lands" similar to Shangri-La) believed to have been created by Padmasambhava in the 9th century as idyllic, sacred places of refuge for Buddhists during times of strife (Reinhard 1978).
