I was recently admonished quite stridently by an acquaintance on the internet when I suggested that the grimoire spirits should be set free and blessed in the name of God. I was called mad. I was warned that there would be horrible repercussions and that I was suggesting letting "all Hell break loose". He also suggested loosing demons into my life but for pity for what it would do to me.
I am not really surprised by this reaction. After all, this person follows a course of occult study based squarely on the Golden Dawn, Thelema, and Franz Bardon. This is the same lineage that views the spirits of the Underworld as demons and evil right off the bat. I try to point out his preset bias to him but he is too deep in it to see these spirits any other way. To him any suggestion that the grimoire and Underworld spirits are anything other than the sworn enemy of humanity is proof that the demons have succeeded in their deceptions.
One thing I've learned about these spirits is that there is a reflective quality to their nature. They take on and reflect back to the magician the qualities that they are expected to have as well as the qualities of the magician themselves. This is why sincerity and purity of heart are so important and, further, why the Confession is part of the process described in the True Grimoire. Sincerity is met with sincerity, belligerence is met with belligerence, and fear is met with fear.
To extend the blessings of God to the demons immediately removes the barrier of demons-equals-enemy that hampers the relationship from the start. It replaces the relationship of adversarial fear with one of respect much more likely to be mutually beneficial. When I make my offerings I will generally extend blessings to the spirits with whom I'm working.
The question of whether or not I have been deceived and I'm going to Hell to spend eternity in torment is irrelevant. The real question is what form my spirituality takes. Do I want to have a practice based in fear and opposition or do I want to spread blessings, even to those unaccustomed to receiving them, strengthening the light of God in the universe? While I walk this earth I get to choose how to live and I choose one of light even when I work with demons.
