A beyul is a sacred hidden valley in remote himalayas that could provide all requirements for settlement. The word beyul is originally a Tibetan word and it follows a very interesting story.
During the eighth century, Guru Padmasambhava, the saint credited with spreading Buddhism into the Himalayas and Tibet, forecasted that in the distant future, when there would be warfare, strife, and unlikely circumstance in the world, good people, and dharma practitioners should travel to Beyuls, situated south of the Tibetan Himalayan range for refuge. He also assigned deities to protect the Beyul. Protective forces manifest as snowstorms, mists and snow leopards. There is said to be 108 Beyuls, out of which many still remain to be discovered. Buddhist texts indicate beyul are discovered when the planet is approaching destruction and the world becomes too corrupt for spiritual practice.
