It isn't that a warrior learns shamanism as time goes by; rather, what he learns as time goes by is to save energy. This energy will enable him to handle some of the energy fields which are ordinarily inaccessible to him. Shamanism is a state of awareness, the ability to use energy fields that are not employed in perceiving the everyday-life world that we know.
Carlos CastanedaWhen one has nothing to lose, one becomes courageous. We are timid only when there is something we can still cling to.
Carlos CastanedaThe humbleness of a warrior is not the humbleness of the beggar. The warrior lowers his head to no one, but at the same time, he doesn't permit anyone to lower his head to him. The beggar, on the other hand, falls to his knees at the drop of a hat and scrapes the floor to anyone he deems to be higher; but at the same time, he demands that someone lower than him scrape the floor for him.
