Tedium is the granddaughter of despondency, and the daughter of slothfulness. In order to drive it away, labor at your work, and do not be slothful in prayer. The tedium will pass, and zeal will come. And if to this you add patience and humility, then you will be rid of all misfortunes and evils.

To the calm haven of heartfelt repentance.

At the same time try to render your heart contrite by the memory of sudden death.
