"High initiation is the fusion of two principles: Atman-Buddhi, through
the five principal Initiations of Major Mysteries. With the first we
achieve the fusion of Atman-Buddhi, and with the fifth, we add the
Manas to this fusion, and so the septenary is reduced to a trinity:
“Atman-Buddhi Manas.” There are a total of Nine Initiations of Major
Mysteries." - Samael Aun Weor, The Zodiacal Course
"The fact that I have previously spoken of five Initiations of Major Mysteries and now I come to speak of nine will appear contradictory to many people. Therefore, I must clarify myself: We fulfill our human evolution with the five Initiations of Major Mysteries. The remaining three Initiations and the degree of “Lord of the World” are of a “Super-Human” nature." - Samael Aun Weor, Occult Medicine and Practical Magic
