Music is the mediator between the life of the senses and the life of the spirit.
Don't only practise your art, but force your way into its secrets.
Do you think I give a damn about your and your pathetic violin?
Only the flint of a man's mind can strike fire in music.
It is my wish that you may have at better and freer life than I have had. Recommend virtue to your children; it alone, not money, can make them happy. I speak from experience; this was what upheld me in time of misery.
The foundation of friendship demands the greatest likeness of human souls and hearts.
