Just pulling from what has been written previously:
Here the OP gives the incantation channeled from Etli’osh: “Sanash Itz Waleep’aye Kantantu”. When I talked with Etli’osh directly I received an alternate form of the incant: “Sanash Alku Itz Waleep’aye Kantantu” Which I have since seen other members of this forum also post.
I wrote in the following post about an effective method I have personally used to invoke dark power:
Remember that power without purpose tends toward self destruction. Anytime you invoke or raise power, especially dark or demonic power, ground it in magick- take that power and make changes in the physical world.
