道德经 29

1If any one should wish to get the kingdom for himself, and to effect this by what he does, I see that he will not succeed. The kingdom is a spirit-like thing, and cannot be got by active doing. He who would so win it destroys it; he who would hold it in his grasp loses it.

2The course and nature of things is such that What was in front is now behind; What warmed anon we freezing find. Strength is of weakness oft the spoil; The store in ruins mocks our toil. Hence the sage puts away excessive effort, extravagance, and easy indulgence.
