If it is a new thought to you that gratitude brings your whole mind into closer harmony with the creative energies of the universe, consider it well, and you will see that it is true. The good things you already have have come to you along the line of obedience to certain laws. Gratitude will lead your mind out along the ways by which things come; and it will keep you in close harmony with creative thought and prevent you from falling into competitive thought.
