Taoism
Taoism was founded by Laozi, the author of the Tao Te Ching. According to Taoist legend, Laozi transmitted the Tao Te Ching at the request of a border guard before departing from China (i.e. from known civilization). He is believed to have lived out the rest of his days in communion with Nature, and some Taoist traditions hold that he achieved immortality. Whether he underwent death or not is not made clear by all parts of the tradition, and if he did, it was in some remote area, far from civilization at that time.
