I have been doing Qui Gong for a short while and have had some good results. I am a bit unclear on a few things however. Are you supposed to breathe the smoke from the actual problem or symtom area or just generally from your body? I also become confused with visualizing the tube at the beginning. Is it supposed to be clear or full of colours? Also, do you need to draw the stomach in when breathing? To me this seems to encourage breathing from the chest rather than through the tummy area. I am probably overanalysing this but would welcome some guidance on these things! Thanks in advance, Shane
