"Guiguzi became of interest to me when I started studying one of Taiwan’s new religions, Weixin Shengjiao (唯心聖教), on which I have written and lectured extensively. It is a central tenet of Weixin Shengjiao that the legitimate successor of the mythical Three Chinese Ancestors was Guiguzi, identified with the Bodhisattva Wang Chan Lao Zu, and that he appeared to the founder of the movement, Grand Master Hun Yuan, mysteriously united with him, and gave to him several books of revelations."
