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 Castaneda
When Carlos Castaneda wrote his books he was trying very hard to find a word that would embody a multitude of modalities from the Shamanic realm. He chose sorcerer because it exemplified knowledge, man of knowledge or one who knows and who was capable at accomplishing extraordinary feats. He also lived completely outside of the box and steered clear of derivatives.
