In Carlos Castenada’s encounters with his teacher Don Juan, Don Juan tells him that a warrior (adept) who trusts his personal power is always impeccable.  If you harness and trust your own spirit it doesn’t matter if you win or lose, accomplish or do not. What matters is being one with your intentions.
This oneness is impeccability. It is timeless and flawless. It is the understanding of all koans and is already enlightenment. There is nothing outside it, beside it, against it or for it.  It stands alone.
