" INWARD OCCUPATION When Satan sees, to the left or right, anyone who is perfect, he becomes ill with envy, for every wretch whose stack has been burnt is unwilling that anyone else’s candle should be lighted. Pay attention and work on perfecting yourself, so that the perfection of others may not grieve you. Beg of God the removal of envy, that God may deliver you from externals, and bestow upon you an inward occupation, which will absorb you so that your attention is not drawn away. "
