The warrior’s final challenge is to balance all the attributes of his path. Once he does that, his purpose becomes inflexible. He is no longer moved by a desperate desire for gain. He is the owner of his will, and can put it to his personal service. When he arrives at that point, the warrior has learned how to be impeccable. And for him to continue being impeccable depends totally on the energy he has accumulated. ~ Carlos Castaneda, Encounters with the Nagual
Carlos goes on to say that impeccability is born of a delicate balance between our internal being and the forces of the external world. It is an achievement that requires effort, time, dedication, and being permanently attentive to the objective, so that the final purpose is never lost from sight. Like a lot of the nomenclature used by Castaneda, the word impeccability takes on a different meaning than the standard dictionary definition. In the dictionary impeccability is defined as the absence of sin, faultless; flawless; irreproachable. Don Juan says; impeccability is nothing else but the proper use of energy.
