But because many endeavor to get knowledge rather than to live well, they are often deceived and reap little or no benefit from their labor.
Thomas a KempisIf thou hadst simplicity and purity, thou wouldst be able to comprehend all things without error, and behold them without danger. The pure heart safely pervades not only heaven, but hell.
Thomas a KempisAnyone who is not totally dead to himself will soon find that he is tempted and overcome by piddling and frivolous things. Whoever is weak in spirit, given to the flesh and inclined to sensual things can, but only with great difficulty, drag himself away from his earthly desires. Therefore he is often gloomy and sad when he is trying to pull himself away from them, and easily gives way to anger should someone attempt to oppose him.
