Only as a warrior can one withstand the path of knowledge. A warrior cannot complain or regret anything. His life is an endless challenge, and challenges cannot possibly be good or bad. Challenges are simply challenges.

Whenever a warrior decides to do something, he must go all the way, but he must take responsibility for what he does. No matter what he does, he must know first why he is doing it, and then he must proceed with his actions without having doubts or remorse about them.

One cannot enter don Juan's world intellectually, like a dilettante seeking fast and fleeting knowledge. Nor, in don Juan's world, can anything be verified absolutely. The only thing we can do is arrive at a state of increased awareness that allows us to perceive the world around us in a more inclusive manner.

There's no way to put a limit on what one may accomplish individually if the intent is an impeccable intent. Don Juan's teachings are not spiritual. I repeat this because the question has come to the surface over and over. The idea of spirituality doesn't fit with the iron discipline of a warrior. The most important thing for a shaman like don Juan is the idea of pragmatism.

A warrior considers himself already dead, so there is nothing to lose. The worst has already happened to him, therefore he's clear and calm; judging him by his acts or by his words, one would never suspect that he has witnessed everything.

A man goes to knowledge as he goes to war, wide awake, with fear, with respect, and with absolute assurance. Going to knowledge or going to war in any other manner is a mistake, and whoever makes it will live to regret his steps.

A warrior must learn to make every act count, since he is going to be here in this world for only a short while, in fact, too short for witnessing all the marvels of it.
