"Blessed are the pure in heart, for they shall see God." Blessed are those who have preserved internal sanctity of soul; who are conscious of no secret deceit; who are the same in act as they are in desire; who conceal no thought, no tendencies of thought, from their own conscience; who are faithful and sincere witnesses, before the tribunal of their own judgments, of all that passes within their mind. Such as these shall see God.
