phoenix-eye, my qigong teacher has always instructed us to be mindfull during practice because otherwise we could hurt ourselves. He tells us never to close our eyes during practice and to never practice when you're not into it. Even the beginning student can accidently do something right and hurt themselves.

For those entering the
realm of Wu with a mind
on Ch'an, the silent
smile awaits them. -
