When the world is at peace, when all things

are tranquil and all men obey their superiors

in all their courses, then music can be

perfected.

When desires and passions do not turn

into wrongful paths, music can be perfected.

Perfect music has its cause. It arises from

equilibrium. Equilibrium arises from

righteousness, and righteousness arises

from the meaning of the cosmos. Therefore

one can speak about music only with a man

who has perceived the meaning of the cosmos.

Music is founded on the harmony between heaven

and earth, on the concord of obscurity and

brightness.
