Imitation of Christ

Propter levitatem cordis et negligentiam defectuum nosrorum non senstimus animæ nostræ dolores, sed sæpe vane reddimus verba, quandomerito flere deberemus. Non est vera libertas, nec bona conscientia, nisi in timore Dei. Felix qui abjicere potest omne impedimentum distractionis, et ad unionem se redigere sanctæ compunctionis. Felix qui a se abdicat quidquid suam conscientiam maculare potest, vel gravare. Certa viriliter. Consuetudo consuetudine vincitur. Si tu scis homies dimittere, ipsi bene dimittent te, tua facta facere. 
 

Through lightness of heart and neglect of our shortcomings we feel not the sorrows of our soul, but often vainly laugh when we have good cause to weep. There is no true liberty nor real joy, save in the fear of God with a good conscience. Happy is he who can cast away every cause of distraction and bring himself to the one purpose of holy compulsion. Happy is he who puts away from him whatsoever may stain or burden his conscience. Strive manfully; custom is overcome by custom. If you know how to let men alone, they will gladly let you alone to do your own works.

Imitation of Christ, I, 21:2
