If he has ten things he wants twenty; if he acquires twenty he seeks thirty; if he has thirty he desires fifty; and so on. Indeed if he had thousands and billions, he would want a kingdom; after that a whole universe; and if the whole universe were given him, his heart would not be satisfied, because the demand of his soul has still not been understood. He goes through life mourning and sorrowing for things he cannot get, not understanding in what lies true gain and true loss.
