After months of searching I found it. Someone mentioned this mantra on another site, and I’ve been hunting it down ever since. It allegedly allows one to summon Azazel to assume your form and copulate with the desired partner while he or she sleeps.
I thought this would interest many here, and I’d love to share it. Unfortunately the mantra is written in a form of Hindi which many of my friends are having trouble translating. Otherwise I would share it for the community here. If anyone has an idea about how to go about decoding it, or wants to try it themselves , I can send you the picture.
