There is a law of the human mind that says man can be either rich or poor.
Would it not be well to consider the command: "Love not sleep, lest thou come to poverty; open thine eyes, and thou shalt be satisfied with bread" (Proverbs, 20:13). The bread of Love and Wisdom alone can bring to us satisfaction.
"Blessed are the poor in spirit: for theirs is the kingdom of heaven" (Matthew, 5:3). To be poor in spirit, is to have lost the sense of all that belongs to both poverty and riches in matter. A total annihilation of the material makes us poor in material knowledge and rich in the spiritual; hence ours "is the kingdom of heaven."
