Now this is an instructor that I could get into! The little exercise in breathwork he supplied had me coughing, laughing, and then crying from lower than my abdomen! Moved mountains of energy blockages from me and even had my spine popping at times! I can only imagine how these techniques and enhance the resonance between crystals tools and practitioners.
