Dante gave a talk about forced possession a while back, and spoke of the many benefits (and dangers) of it. He stated that an entity can possess the magician and then instruct him/her how to perform certain rituals and attain certain physiological states. The entity would achieve these feats, while allowing the host to stay conscious to witness how it is done.
Is this only reserved for skilled magicians, or can/will EA or Dante perform this on a new magician in the hopes that the new magician can learn from the demon/angel first hand how to enter the theta gamma sync and soul travel etc.
I know its seems like overkill, but it would be a great boost to have.
