The Tao doesn't take sides; it gives birth to both good and evil. The Master doesn't take sides; she welcomes both saints and sinners. The Tao is like a bellows: it is empty yet infinitely capable. The more you use it, the more it produces; the more you talk of it, the less you understand. Hold on to the center.
If you see what is small as it sees itself, and accept what is weak for what strength it has, and use what is dim for the light it gives then all will go well. This is called Acting Naturally.
Peacefulness is an inner sense of calm - it comes from becoming still - in order to reflect and meditate on our inner wisdom and receive answers. A peaceful heart is one that is free from worry and rouble. It's becoming quiet so we can look at things quietly so we can more clearly understand them and thus come up with creative solutions. It is learning to live in the present. Freedom from desire leads to inner peace.
The wise person dines on something more subtle: He eats the understanding that the named was born from the unnamed, that all being flows from non-being, that the describable world emanates from an indescribable source.
