To worry is to become accessible, unwittingly accessible. And once you worry you cling to anything out of desperation; and once you cling you are bound to get exhausted or to exhaust whoever or whatever you are clinging to.
Carlos CastanedaWhenever you are in the world of the tonal, you should be an impeccable tonal; no time for irrational crap. But whenever you are in the world of the nagual, you should also be impeccable; no time for rational crap. For the warrior intent is the gate in between. It closes completely behind him when he goes either way
