Peace is divine, but men have misused its name.
The Earth is one constituent of the universe, but because men see it underneath Heaven, they regard Heaven as its antagonist; for division is the first function of Nature. But just as the two eyes see two images, which are made one in the optic thalamus, so should man forget antagonism and create unity in himself.
Peace is the reconciliation of Heaven and Earth. But to say this to the worldly is a waste of breath, for the worldly man does not know the meaning of either his Heaven or his Earth. His body came from earth, and his Spirit from Heaven desiring to know earth, but the body has denied the Spirit which gives it life. So man looks for God in the starry sky, and makes the intellectual mistake of dividing the Spirit of Heaven from the Spirit of Earth.
