A vessel is formed from a lump of clay with care, however, it is the empty space within the vessel that makes it useful.

The best soldiers are not warlike; the best fighters do not lose their temper. The greatest conquerors are those who overcome their enemies without strife. The greatest directors of men are those who yield place to others. This is called the Virtue of not striving, the capacity for directing mankind; this is being the compeer of Heaven. It was the highest goal of the ancients.

Keep your mouth shut, and close up the doors of sight and sound, and as long as you live you will have no vexation. But open your mouth, or become inquisitive, and you will be in trouble all your life long.

Goodness in words creates trust, goodness in thinking creates depth, goodness in giving creates love.

Arms are instruments of ill omen.... When one is compelled to use them, it is best to do so without relish. There is no glory in victory, and to glorify it despite this is to exult in the killing of men.... When great numbers of people are killed, one should weep over them with sorrow. When victorious in war, one should observe mourning rites.

Excellent soldiers are not furious.

Harmony is called the eternal. Knowing the eternal is called clarity.
