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 rule of thumb for a warrior is that he makes his decisions so carefully that nothing that may happen as a result of them can surprise him, much less drain his power.

Conclusions arrived at through reasoning have very little or no influence in altering the course of our lives.

You're chained to you reason ... Understanding is only a very small affair, so very small

Warriors do not win victories by beating their heads against walls, but by overtaking the walls. Warriors jump over walls; they don't demolish them.

There is no way to escape the doing of our world, so what a warrior does is to turn his world into his hunting ground. As a hunter, a warrior knows that the world is made to be used. So he uses every bit of it. A warrior is like a pirate that has no qualms in taking and using anything he wants, except that a warrior doesn't mind or he doesn't feel insulted when he is used and taken himself

Fright is something one can never get over. When a warrior is caught in such a tight spot he would simply turn his back to the ally without thinking twice. A warrior cannot indulge thus he cannot die of fright. A warrior allows the ally to come only when he is good and ready. When he is strong enough to grapple with the ally he opens up his gap and lurches out, grabs the ally, keeps him pinned down and maintains his stare on him for exactly the time he has to, then he moves his eyes away and releases the ally and lets him go. A warrior, my little friend, is the master at all times
