Never heard of it.
Read through the comment section. Didn’t see much in the way of success stories.
From what i gather, this ritual is a variation of the Necronomicon where JS evokes the spirit and your higher self. That seems like it can work - calling in a person’s higher self is powerful for reprogramming minds at a subconscious level.
I wrote a version of the Necronomicon ritual straight out of the book. You can find it here. If you haven’t bought the Astarte Sex Slave Ritual (or can’t afford it), the Necronomicon ritual is there for you to do yourself.
