However nice this may seem, you are in trouble. Get help fast. But, to the best of my knowledge, ALL of these are splinters or splinters of splinters of the original. Each splinter group had a special axe to grind and is, to that extent, not representative of the thrust of the original. Even most splinters of the original have undergone disruptions and distortions.
Some current groups seem to claim a lot more.
Such claims should be questioned. My respect for Israel Regardie as historian is great. This was the Regardie I knew personally, and read avidly. Regardie himself explicitly discounted such ideas to the last. I am not in that area.
