Chang Tzu om stillhetsmeditasjon

"See nothing; hear nothing; guard your spirit in quietude and your body will go right of its own accord.

"Be quiet, be pure; toil not your body, perturb not your vital essence, and you will live for ever.

"For if the eye sees nothing, and the ear hears nothing, and the mind thinks nothing, your spirit will stay in your body, and the body will thereby live for ever.
