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.
Carlos CastanedaIn a world where death is the hunter, my friend, there is no time for regrets or doubts. There is only time for decisions.
Carlos CastanedaA warrior is a hunter. He calculates everything. That's control. Once his calculations are over, he acts. He lets go. That's abandon. A warrior is not a leaf at the mercy of the wind. No one can push him; no one can make him do thingsagainst himself or against his better judgment. A warrior is tuned to survive, and he survives in the best of all possible fashions.
Carlos CastanedaAnd so you're afraid of the emptiness of your friend's life. But there's no emptiness in the life of a man of knowledge, I tell you. Everything is filled to the brim and everything is equal.
Carlos CastanedaA man of knowledge chooses a path with a heart and follows it and then he looks and rejoices and laughs and then he sees and knows.
