Max Heindel,
Simplified Scientific Astrology…
(1919)
“ Thus, when you have given an astrologer the data of your birth, you have given him the key to your innermost soul, and there is no secret that he may not ferret out. This knowledge may be used for good or ill, to help or hurt, according to the nature of the man. Only a tried friend should be trusted with this key to your soul, and it should never be given to any one base enough to prostitute a spiritual science for material gain. ”
