" When knowledge serves our fears, it can make the sensible seem satanic, the satanic sensible. And yet knowledge, the single greatest devilry for humanity, can also be its savior. It’s up to each of us to recognize knowledge as the voice in our own head—the voice we have come to trust and obey. It’s up to each of us to modify that voice and to reform the tyrant. For, in the process of mastering knowledge, we have become knowledge. We have become the tyrant, the tempter, prompting fear with every opportunity. By redeeming knowledge, we redeem ourselves. "

― Miguel Ruiz , The Toltec Art of Life and Death
