" What is a pure heart? It is meek, humble, guileless, simple, trusting, true, unsuspicious, gentle, good, not covetous, not envious, not adulterous. My soul! remember thy heavenly dignity and do not be disturbed by corruptible, worthless things. Honour also in other people their heavenly dignity, and do not dare offend or hate them for any perishable cause; love with all thy might that which is spiritual and heavenly, and despise that which is material, earthly. "
