Don't think you have a black magician attacking you? You very well may. Every Gnostic student should at least try the technique found in "The Divine Science" (Logos, Mantra, and Theurgy). Look in the index under sorceresses. I was having terrible dreams, primarily of people attacking me, so, as it says in "The Divine Science," I put a pair of scissors down in the form of a cross and scattered some of these Black Mustard Seeds on the floor. I stopped having the nightmares, and from what I can tell, the entity that was attacking and still is trying to can no longer harm me!
I received the seeds in neatly packed envelope. I look forward to use it as recommended by master Samael.
