A poor man is a man having no qualities, no force, no strength, no generosity. He is also a miserable, unhappy man. Moreover, one is unhappy only when one is not generous— if one has a generous nature which gives of itself without reckoning, one is never unhappy. It is those who are coiled up on themselves and who always want to draw things towards themselves, who see things and the world only through themselves — it is these who are unhappy. But when one gives oneself generously, without reckoning, one is never unhappy, never. It is he who wants to take who is unhappy; he who gives himself is never so.
