"If ye go into cities or kingdoms or countries, proclaim first unto them, saying: Search ever and cease not, until ye find the mysteries of the Light which will lead you into the Light-kingdom. Say unto them: Beware of the doctrines of error. For many will come in my name and say: It is I. And it is not I, and they will lead many astray.

What mysteries they shall give."Now, therefore, unto all men who come unto you and have faith in you and hearken unto your words and do what is worthy of the mysteries of the Light, give the mysteries of the Light and hide them not from them. And unto him who is worthy of the higher mysteries, give them, and to him who is worthy of the lower mysteries, give them, and hide not anything from any one.
