Imitation of Christ

Religiosus negligens et tepidus habet tribulationem super tribulationem et ex omni parte patitur angustiam, quia interiori consolatione caret, et exteriorem quærere prohibetur. Religiosus extra disciplinam vivens gravi patet ruinæ. Qui laxiora quærit et remissiora, semper in angustiis erit, quia unum aut reliquum displicebit sibi.
 

He who is earnest receives and bears well all things that are laid upon him. He who is careless and lukewarm has trouble upon trouble, and suffers anguish upon every side, because he is without inward consolation, and is forbidden to seek that which is outward. He who is living without discipline is exposed to grievous ruin. He who seeks easier and lighter discipline shall always be in distress, because one thing or another will give him displeasure.

Imitation of Christ, I, 25:7
