Everything works for a little while—works until it doesn’t, and at some point, a pattern is revealed. That which is not God is snake oil. Snake oil is magick until it isn’t. Cures depend on us being sick, a snake-eating-its-own-tail situation. Our bodies know when we’ve bought the snake oil. They will eventually reject what is not true.
