The book Tao Te Ching was written by the great Chinese spiritual adept, Lao Tse, about 2500 years ago. In that incarnation, Lao Tse was a disciple of non-incarnate Huang Di and achieved full spiritual self-realization. At the present time, Lao Tse provides spiritual help to incarnate people. The Tao Te Ching is one of the most fundamental texts on the philosophy and methodology of spiritual development.
