There is no thing as a man who does not create mathematics and yet is a fine mathematics teacher. Textbooks, course material-these do not approach in importance the communication of what mathematics is really about, of where it is going, and of where it currently stands with respect to the specific branch of it being taught. What really matters is the communication of the spirit of mathematics. It is a spirit that is active rather than contemplative-a spirit of disciplined search for adventures of the intellect. Only as adventurer can really tell of adventures.

Follow your heart always, and remember to take your head along with you.

My psychology belongs to everyone.

My difficulties belong to me!

Trust only movement. Life happens at the level of events, not of words. Trust movement.

God who is eternally complete, who directs the stars, who is the master of fates, who elevates man from his lowliness to Himself, who speaks from the cosmos to every single human soul, is the most brilliant manifestation of the goal of perfection.

The goal of the human soul is conquest, perfection, security, superiority.
