So when you feel a cooling for spiritual things and occupations and generally for all divine things, enter deeply into yourself and examine carefully why it has happened; and, if it is your fault, hasten to eliminate and efface it, not so much because you are anxious for the return of spiritual delights, but rather because you want to destroy in yourself all that is unfitting and not pleasing to God. If you find nothing of this kind, submit to God’s will, saying to yourself: ‘God has so decided: let Thy will be done on me, O Lord, weak and unworthy as I am.’ Then be patient and wait, never allowing yourself to deviate from the habitual order of your spiritual life and spiritual works and exercises. Overcome the lack of taste for them, which has assailed you, by forcibly making yourself practice them, paying no attention to thoughts which try to distract you from your efforts by suggesting that this occupation is useless; drink willingly your cup of bitterness, saying to the Lord: ‘See my humility and my efforts, O Lord, and deprive me not of Thy mercy,’ and let your efforts be inspired by the faith that this cup comes from God’s love for you, because He desires you to attain a greater spiritual perfection.
