and the purging is very important. i puked for about 3-4 hours. then was empty, THEN it hit me. had 3 shamans chanting around me, every new chant brought on another spirit. Each one having a different personality. Some friendly and comforting, and some honestly, scared the shit outta me. but the shamans were in complete control, when they saw how each effected me they altered the chant to subdue, or expand the energy of each spirit. Done right, it can almost make you a little schizophrenic. When life decisions are on my mind, there is a convorsation between the spirits that stuck with me, and my mind. kind of like the angel/devil on the shoulders... but its more like 4-5 of them. if you have a chance to do this properly, and have a very strong, stable mind, Do it. if you think you may lose control, dont.
