"Well I will only tell how to raise Kundalini to those who are ready."
Withholding publicly available knowledge? How's that been going for you? I see. Well, it's about to go terribly from here on out.
While the study of the kundalini sort of straddles the line between theory of the universe and practical magick, I believe the following quote from Dion Fortune in The Mystical Qabalah, is rather appropriate, emphasis mine.
"No one is going to be persecuted nowadays for their studies in unorthodox sciences, so there can be but one purpose in withholding teaching that relates solely to the theory of the universe and the philosophy arising therefrom, and in no way to the methods of practical magic, and that purpose is to retain a monopoly of the knowledge which confers prestige, if not power. For my part I believe that this selfishness and exclusiveness is the bane of the occult movement rather than its safeguard. It is the old sin of retaining the knowledge of God in the hands of a priesthood and denying it to all outside the sacred clan; justifiable enough when the people were savages, but unjustifiable in the case of the modern student.
