“really matter what you put in there, it is foul-smelling stuff. Pepper, sulfur, vinegar, turned milk, or fish heads if you want. One of my favorite passages in the Bible is actually in the Apocrypha, in the Book of Tobit, and it is the story of Tobias and the Angel. There’s one part of the story of Tobias and the Angel where they’re exorcising evil spirits from a house, and they make an exorcism incense, and one of the ingredients is fish heads. The instructions are, you make this incense, you take it into the house, light it, leave the house and don’t go back for three days, because nothing wants to be in there for three days. It’s a foul stench of exorcism, and so this ritual uses a foul stench-filled incense. It doesn’t matter what it is, as long as it’s unpleasant and acrid. That’s why vinegar is one of the important ingredients because it makes it acrid. So you’ve got his nasty, acrid smoke that stings your eyes, and you basically go on a rant. You wear a rough robe, of horsehair or sack”
