When you asked this question i had only briefly heard of the ritual. So i did sone studying so i can cone back and give you my take on it. At first impression i thought that Abraham was the same Abraham the jew from the bible. The i saw that the grimiore was a story abput abraham of worms, germany. I had been aware of the ritual only because i heard crowley bought the house on Loch Ness specifically for the ritual.

Would i ever try to perform it? I doubt it. I am not very much into ritual or ceremonial magick

I wish i had the patience.
