No one is justified in seeking an excuse for ingratitude in his own weakness or poverty, or in saying, “What am I to do, and how? When can I repay my debt to my superiors the lords of heaven and earth?” Avaricious as you are, it is easy for you to give them thanks, without expense; lazy though you be, you can do it without labour. At the same instant at which you received your debt towards them, if you wish to repay it, you have done as much as anyone can do, for he returns a benefit who receives it with good will.
