Travel of Honey Moon
Shangri-La is a fictional place in the Kunlun Mountains (昆仑山) described in the 1933 novel Lost Horizon by English 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, particularly a mythical Himalayan utopia – an enduringly happy land, isolated from the world. In the novel, the people who live at Shangri-La are almost immortal, living hundreds of years beyond the normal lifespan and only very slowly aging in appearance.
In the ancient Tibetan scriptures, the existence of seven such places are mentioned as Nghe-Beyul Khembalung.[1] 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).
