I have read "The lost teachings of Atlantis". It's an older book but about a man's journey going back to his past as a lost young lad that decided to travel to nowhere specific and ended up hiking in the forest in Tibet and came across a secret sacred Buddhist temple and was invited to join the monks in a spiritual opening journey and learn the sacred ancient traditions and knowledge that originated in Atlantis and the teachings of the "Law of One". Since then, the Chinese (CPP) have destroyed the temples and their teachings and he was instructed by his spiritual teachers to write a book about his experience and knowledge so that the traditions can live on.
