“If they are unwilling to give, they should at least lend with all readiness and alacrity, not with the prospect of receiving anything back except the principal. … In place of the interest which they determine not to accept they receive a further bonus of the fairest and most precious things that human life has to give, mercy neighborliness, charity, magnanimity, a good report and good fame. And what acquisition can rival these? Nay, even the great king will appear as the poorest of men if compared with a single virtue. For his wealth is soulless, buried deep in store-houses and recesses of the earth, but the wealth of virtue lies in the sovereign part of the soul, and the purest part of existence.”

Be Generous!
