All 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.
ConfuciusIf one learns from others, but does not think, one will be bewildered. If, on the other hand, one thinks but does not learn from others, one will be in peril.
Confucius
