The spirit is something to be enjoyed. It is not a harsh discipline. And I think people should take some time everyday for some kind of moving meditation, like Qigong or Tai Chi.
Stillness and action are relative, not absolute, principles. It is important to find a balance of yin and yang, not just in qigong, but in everyday life. In movement, seek stillness and rest. In rest, be mindful and attentive.
Qigong is a jewel that has many facets.
Qigong is the art and science of refining and cultivating internal energy.
If you want to be healthy and live to one hundred, do qigong.
I think Dogen can be a very good introduction for people who want to meditate in whatever way, whether it's yoga, qigong, or Tibetan. It can help widen and deepen anyone's meditation experience.
For optimal health, we need body and spirit, exercise (ming) and meditation, awareness of the inner world and the outer. In other words, health requires balance and moderation. The goal of qigong may be summarized as xing ming shuang xiu,spirit and body equally refined and cultivated. Cultivate your whole being, as you would cultivate a garden with attention, care, and even love.
