For a while, I have felt that something was missing from the Witness method that Bill Harris of Holosync mentions. Just watch the emotions, but there never seemed to be a finishing point to that. I listened to a Sounds True podcast with Raphael Cushnir, the author of "The One Thing Holding You Back", was intrigued, and found that my local library had the book.
Raphael Cushnir touches on the witness with "Yeah, But" excuse number six, mentioning that emotions need more than witnessing and that they need to be felt and given complete awareness. This actually seems to match what I recently read in Eckhart Tolle's "The Power of Now" and feels more like the shadow work I've heard mentioned in various places.
Raphael Cushnir talks about emotional connection and the 2 x 2 method for accomplishing that and gives tips, examples, and stories of working with it. It is something I am going to experiment to see what happens, but it does feel right to me. I would definitely recommend checking his book out.
