I have learned silence from the talkative, toleration from the intolerant, and kindness from the unkind yet, strange, I am ungrateful to those teachers.

It is the supreme art of the teacher to awaken joy in creative expression and knowledge.

If I am walking with two other men, each of them will serve as my teacher. I will pick out the good points of the one and imitate them, and the bad points of the other and correct them in myself.

You have to grow from the inside out. None can teach you, none can make you spiritual. There is no other teacher but your own soul.

I have come to believe that a great teacher is a great artist and that there are as few as there are any other great artists. Teaching might even be the greatest of the arts since the medium is the human mind and spirit.
