高台教
"Cao Đài" originates in the spirit communication between man and spiritual beings. At the beginning, it was the dignitaries in Hiệp Thiên Đài, also appointed mediums by God, who received the spirit messages from heaven. Consequently, all of the scriptures as well as Cao Đài Law come from "Hiệp Thiên Đài". Playing an important role in the establishment or modification of other Cao Đài laws, "Hiệp Thiên Đài" is very important in Cao Đài Church, like the brain in a human body.
