I am wondering about the roles that each part of the human trinity play and how to better relate that to my magical skill. I have come across several documents that briefly go into the functions of the body, soul, and mention that the spirit is there (or that we exist on the Physical, Astral, and Mental).
From what I can gather (and please correct me if I am wrong), the physical body acts as a focal point which helps many different powers to merge to carry out a magical act, acts as a temple, and acts as a powerhouse for magical acts. The soul acts in ways that the body cannot (astral projection, creating temples, meeting entities, etc). The spirit on the other hand, I rarely come across any good material on. I think that if I knew what each of the parts play, I could make my practice a bit more effective. Has anyone come across any material that gives an in depth description of their roles?
