And so are the heart-qualities. Different people have different qualities of the heart, and the knower of the heart will treat each differently. But since we do not think about this aspect we take every man to be the same. Although every note is a sound, they differ in pitch, in vibrations; and so every man differs in the pitch, the vibrations, of his heart. According to the vibrations of his heart he is either spiritual or material, noble or common. It is not because of what he does, nor because of what he possesses in this world; he is small or great according to how his heart vibrates.
