He who has money and goods considers himself secure, is happy and unafraid, as if he were sitting in the midst of Paradise. And again, he who has none doubts and is despondent as though he knew of no God. For you will find very few who are of good cheer, who neither mourn nor complain if they do not have mammon. This love of money clings firmly to human nature to the very grave.
