A man may perform astonishing feats and comprehend a vast amount of knowledge, and yet have no understanding of himself. But suffering directs a man to look within. If it succeeds, then there, within him, is the beginning of his learning.

It is tragic-comic to see that all this knowledge and understanding exercises no power at all over men's lives, that their lives do not express in the remotest way what they have understood, but rather the opposite.

If I had a humble spirit in my service who, when I asked for a glass of water, brought me the world's costliest wines blended in a chalice, I should dismiss him, in order to teach him that my pleasure consists, not in what I enjoy, but in having my own way.
