The way the story goes, when one of my teacher's teachers first learned sitting meditation, the instructions he received were terse:
Sit upright and balanced with the legs crossed. Think nothing, do nothing.
This kind of simplicity of instruction is typical of Zen training, and of genuine meditation in general. You may think that following such an instruction is out of your reach, but if you've practiced Qigong with me, you actually have an experience of it already!
The instruction is about what you do with your will and your effort. It's not about stopping thoughts or freezing your body, though some practitioners do make that mistake. Consider that "thinking nothing" doesn't have to mean thoughts don't arise, and "doing nothing" doesn't mean that things stop happening. The instruction is about letting your effort rest, not forcing your thoughts any particular way, not forcing your actions any particular way, and allowing things to happen spontaneously. The wisdom of this principle is simple: when we abide in this state, our bodies and minds (and if you follow Buddhist and Daoist thinking, the whole world) naturally change to become healthier, stronger, and more harmonious.
We do this when we practice Qigong. It's the meditative state itself, relaxation and awareness, where we begin every session. It's the state of being that manifests as Flowing Breeze, Swaying Willow. It's both the method of correct practice and the result of correct practice. What would it feel like to live in this state all day long? How do you think your life would change?
Let this short writing remind you of what's important in good Qigong practice, and maybe what's important for life in general as well.
