" Early in its education every mind learns how to use words to threaten, to punish, and to destroy. If that fact sounded harsh to his apprentices, he had only to remind them of how they spoke to themselves—how they attacked themselves on a daily basis. The mind is its own kind of predator, whether it belongs to the body of a bashful woman or a brawny man. "

― Miguel Ruiz , The Toltec Art of Life and Death
