From Cao Dai’s Collection of Divine Messages, Vol. 1

Over 80 years ago, a new religion was founded with the name Cao Đài in the country of Âu Lạc (Vietnam) and has quickly grown to become the third largest religion in this country. Cao Đài recognizes that the ultimate goal of all true religions is the same; to teach humankind to live peacefully and compassionately with all sentient beings, and to realize our divine origin. The term Cao Đài literally means "Supreme Palace", referring to the place where God reigns over the universe, and was also the name God used to impart Hiers divine instructions in the creation of Cao Đài.
