Transmit the established facts; do not transmit words of exaggeration. If you do that, you will probably come out all right.
ZhuangziAll existing things are really one. We regard those that are beautiful and rare as valuable, and those that are ugly as foul and rotten. The foul and rotten may come to be transformed into what is rare and valuable, and the rare and valuable into what is foul and rotten.
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
