Oh, I just had the best so far exercise since the retreat. It's because of this thread and the resultant clarification and sorting out of ideas I had about Qigong. Mainly the purpose and visualization for each exercise. I had been mixing it all up since I got home.
As for the emptiness: I find that Chunyi's phrase "Go inside" instantly changes my perspective on any visualization. It brings me inside my head and the experience becomes a totally surrounding one. Not a third party or vantage point experience. This is a more body oriented experience and much more closely linked so some of my best meditation experiences at the retreat.
Thanks again for the thread contributions, and sending love,
