“ Crowley lists various types of blood as acceptable ingredients within a Cake of Light. He writes: “Of the moon” refers to monthly menstrual blood. “Of a child” refers to fluid from sexual intercourse. “From the host of heaven” refers to semen. Crowley continues, “Of enemies; then of the priest or of the worshippers” is self-explanatory. “Last of some beast” refers to animal blood; the least controversial since many foods are made with the substance.” Still kind of gross though..
