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.

When one has nothing to lose, one becomes courageous. We are timid only when there is something we can still cling to.

A warrior takes responsibility for his acts, for the most trivial of acts. An average man acts out his thoughts, and never takes responsibility for what he does.

Never take a path that has no heart in it. You can't lose if your heart is in your work, but you can't win if your heart is not in it.

The world doesn't yield to us directly, the description of the world stands in between. So, properly speaking, we are always one step removed and our experiences of the world is always a recollection of the experience. We are perennially recollecting the instant that has just happened, just passed. Re recollect, recollect, recollect.

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.

The greatest flaw of human beings is to remain glued to the inventory of reason. Reason doesn't deal with man as energy. Reason deals with instruments that create energy, but it has never seriously occurred to reason that we are better than instruments: we are organisms that create energy. We are bubbles of energy.
