Tao Te Ching: Chapter 26
If 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.
The course and nature of things is such that
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.
