"Then thou shalt make great progress if thou keep thyself free from all temporal care. Thou shalt lamentably fall away if thou set a value upon any worldly thing. Let nothing be great, nothing high, nothing pleasing, nothing acceptable unto thee, save God Himself or the things of God. Reckon as altogether vain whatsoever consolation comes to thee from a creature. The soul that loveth God looketh not to anything that is beneath God. God alone is eternal and incomprehensible, filling all things, the solace of the soul, and the true joy of the heart."
--- Thomas A Kempis, The Imitation of Christ
