I have studied several faiths, religions, beliefs and practices. My question is of the 9 gods or goddesses that the left hand follow. Where is the original organization of these 9? I have looked and looked studied and can’t seem to find the origin of the 9? Could you clarify this for me? After 21 years of practice of the arts I’ve never been stumped like this. Thank you and may the power of the Left Hand grow.
