" Know thou that the love of thyself is more hurtful to thee than anything in the world. According to the love and inclination which thou hast, everything more or less cleaveth to thee. If thy love be pure, sincere, well-regulated, thou shalt not be in captivity to anything. Do not covet what thou mayest not have; do not have what is able to hinder thee, and to rob thee of inward liberty. "

― Thomas à Kempis , The Imitation of Christ
