There are three things against which the wise man guards: lust when young, quarrels when strong, and covetousness when old.
ConfuciusAll things are nourished together without their injuring one another. The courses of the seasons, and of the sun and moon, are pursued without any collision among them. The smaller energies are like river currents; the greater energies are seen in mighty transformations. It is this which makes heaven and earth so great.
Confucius
