Most magickal traditions use some form of divine embodiment in their rituals in which a priestess or a priest becomes for a time the vehicle for the presence of one of the Great Ones. When it works, it is awe-inspiring, and can act as a great catalyst for change. When it fails, and is no more than role playing or ritual theater, it can encourage cynicism, disillusionment, and diminished expectations of what is possible in ritual. The strengths and the weaknesses of assumption of god forms, drawing down, aspecting, and divine possession will be compared to each other.
