The 72 angels of the Shemhamphorash are based on Kabballah. They are derived using a kabbalistic formula from the script of Exodus and their powers are attributed according to Gematria and the Kabballah. Far from being dark spirits, they are functions of the Source/ and in my experience they bring a sense of calm stillness when evoked. Other people have reported incredibly powerful and uplifting experiences when we've worked with them in the past. I will probably provide updates on it through posts on here once we start.
