"All confess that they must die, and die only once and that nothing is of greater importance than to die well; because on death depends whether we shall be forever in bliss or forever in despair. All know that our eternal happiness or our eternal unhappiness depends on leading a good or a bad life. How then does it happy that the greater part of Christians live as if there were never to die, or as if to die well or ill were of little moment! ...
'Remember thy last end, and thou shalt never sin.' (Eccl. 7:40)"
- St. Alphonsus Liguori: Preparation for Death
These dispositions are believed to be written by St. Louis Marie de Montfort
