When you practice tai chi or qigong today, treat your practice as a meditation.
Know that you are breathing, aware of each in and out breath. Try to be aware of your whole body as you move through the postures, the form. Know where you are in each moment of practice. Then, do it again.
When you know where you are, nothing can move your mind. You can’t be thrown off-balance physically or emotionally. Working on this a little every day, makes your life more peaceful because you slow down and don’t have the stress of feeling off-balance.
