Cognitive behavior therapy. I understand the meditation of hindus etc. could be conceived as a possibility that an empty vessel is an invitation or a lowering of the guard to evil spirits. but it could also show someone that they r possessed of evil thoughts. let go of your hate. grudges. forgiving your enemies. these are righteous causes doesnt mean be a dopey hippie. I'd study Jung. Hoping to get there myself. But the Bible, Orthodox, is the accumulation of great knowledge, psychology, history, etc.

it was there all along.
