Hui-Zi said to Zhuang-Zi, 'I have a large tree, which men call the Ailantus. Its trunk swells out to a large size, but is not fit for a carpenter to apply his line to it; its smaller branches are knotted and crooked, so that the disk and square cannot be used on them. Though planted on the wayside, a builder would not turn his head to look at it. Now your words, Sir, are great, but of no use;-- all unite in putting them away from them.'
Zhuang-Zi replied, 'Have you never seen a wildcat or a weasel? There it lies, crouching and low, till the wanderer approaches; east and west it leaps about, avoiding neither what is high nor what is low, till it is caught in a trap, or dies in a net. Again there is the Yak, so large that it is like a cloud hanging in the sky. It is large indeed, but it cannot catch mice. You, Sir, have a large tree and are troubled because it is of no use;--
why do you not plant it in a tract where there is nothing else, or in a wide and barren wild? There you might saunter idly by its side, or in the enjoyment of untroubled ease sleep beneath it. Neither bill nor axe would shorten its existence; there would be nothing to injure it. What is there in its uselessness to cause you distress?'
each and every thing is perfect
