I would like to know about the stand of the Star of Azazel concerning Blood sacrifices, be it the use of our own human blood or blood from animals as in many necromancy rites. And the offerings to the Demons on the altar.
SOA's policy is strongly against harming other beings, especially so in the context of devotional or occult practice. Our philosophy sees such sacrifices both unethical and giving only short term help, because according to our thought, the greater price must also be paid. Giving pain or taking life will hinder, not help, our own development & the cosmic path of return to perfect night in the long run; such is the credo of all the paths of ascension.
Thus, if it becomes known that a brother or a sister performs a blood sacrifice by killing or harming another being, human or animal, it is most likely that such a member will be expelled, for it is against the very basic ethics of the Star of Azazel. On the other hand, giving one's own blood is more complicated, and would remain as an issue of open debate. Some brethren would approve, some disapprove, but either way it would remain as one's personal choice.
Another thing are the goals of such a sacrifice. Those kinds of elementals (spirits, demons) that are attracted to spilled blood are the kind with which beneficent work is not easily done. That kind of pact between the one who sacrifices & the spirits is almost always contrary to our goals of releasing souls from the blinds of the lesser gods, collectively called the Demiurge, or more neutrally materialism, or by other names.
Personally, I stopped making blood sacrifice to any entities when I fully understood that the microcosmic body is not actually mine to give, but is a compound thing made of goetic entities. (See Fosforos, footnote 49.)
