All our knowledge has its origin in our perceptions

The knowledge of all things is possible

Simplicity is the ultimate form of sophistication

The painter has the Universe in his mind and hands.

One can have no smaller or greater mastery than mastery of oneself.

You will never have a greater or lesser dominion than that over yourself...the height of a man's success is gauged by his self-mastery; the depth of his failure by his self-abandonment. ...And this law is the expression of eternal justice. He who cannot establish dominion over himself will have no dominion over others.
