In my experience of healing myself inner shamanism, you don't have a chance of healing yourself if you don't engage with your I AM Self on multiple levels (this needs a mentor or an extremely extensive book - this book doesn't currently exist). How many people in the world could mentor this? I have found two, one of them is myself.
Bodywork was also crucial and allowing myself to FEEL everything but the I AM work is more powerful by a factor of 1000+ times than anything else.
