I bought universal magick but never used it actually the book looks a bit strong.
The difference from the success spell does not affect your future, you do not need to enter a 14-month period, etc. universal magic works on the present.
Gerald J. Schueller published some books (Llewellyn’s High Magick Series). Unsure if these are still available except expensive, second-hand.
And be careful. OK? Enochian entities aren’t really nice. Just saying.
