I've been learning this Qigong routine and am starting to really like it. The movements are very smooth and gentle, and the sequence is not hard to learn. It can be completed in 10 minutes or less which is ideal if your energy level is low or your pressed for time.
If you watch the Enya Adiemus video on YouTube ..it shows energy trailing her movements. I think it's a good visual example of how energy moves in Qigong also.
