From within a Chinese cosmological world view--when we practice qigong which has been passed down to us through many generations of adepts, we are receiving the collective "perfected" form of all the people in the lineage receding back through time. This practice resolves us (zheng). It resolves our fate (ming). It gives us a way to literally embody resolved action. If we remain sensitive to this process, the result --the fruition of practice -- is appropriate conduct in our daily lives.
This also works in the other direction. Imagine for a moment that the qigong we are doing seems to overwork our liver. Perhaps it is because someone in our lineage drank to much alcohol and her conduct is manifesting itself in the qigong we were taught and practice. If we keep precepts and practice appropriate action, our own healthy liver and our own healthy habits will eventually change the qigong practice itself, thus resolving the past and passing on to our students a healthier qigong practice. So the practice of qigong not only influences our ancestors and the lineage of our teachers, but also influences our students and our decedents.
Now I'm not a lineage fundamentalist, and I'm not a puritan either. But I think it is a little sad that just because Westerners don't understand Chinese cosmology, they toss it out like so much flotsam and jetsam.
In response to all the hucksterism and Qijocks in the qigong and yiquan worlds we are seeing more and more American qigongers and marital artists who reject any traditional Chinese ideas about how studying a martial art could improve your humanity or your health.
We now have qigong Atheists with a puritanical edge.
