Water becomes clear and transparent when in a quiescent stage. How much the more wonderful will be the mind of a sage when poised in quiescence! It is the mirror of heaven and earth, reflecting the ten thousand things.
ZhuangziDo not seek fame. Do not make plans. Do not be absorbed by activities. Do not think that you know. Be aware of all that is and dwell in the infinite. Wander where there is no path. Be all that heaven gave you, but act as though you have received nothing. Be empty, that is all.
ZhuangziTao is the source of both fullness and emptiness. But it is itself neither fullness nor emptiness.
ZhuangziThe mind remains undetermined in the great Void. Here the highest knowledge is unbounded. That which gives things their thusness cannot be delimited by things. So when we speak of 'limits', we remain confined to limited things. The limit of the unlimited is called 'fullness.' The limitlessness of the limited is called 'emptiness.' Tao is the source of both. But it is itself neither fullness nor emptiness
