If you put on more garments, the cold cannot reach you. Similarly, increase your patience and concentration and even great injuries cannot vex your mind.
Leonardo da VinciIn rivers, the water that you touch is the last of what has passed and the first of that which comes; so with present time.
Leonardo da VinciYou 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.
Leonardo da Vinci
