Not he is chaste in whom shameful thoughts stop in time of struggle, work and endeavor, but he who by the trueness of his heart makes chaste the vision of his mind not letting it stretch out towards unseemly thoughts.
Was there ever anyone of any breeding who dared to speak the name of Holy Mary, and being questioned, did not immediately add, 'the Virgin'? For by such added names the positive proofs of merit are apparent... And to the Holy Mary, Virgin is invariably added, for that Holy Woman remains undefiled.
If anyone wants to drive out the demons, he must first subdue the passions, for he will banish the demon of the passion which he has mastered. For example, the devil accompanies anger; so it you control your anger, the devil of anger will be banished. And so it is with each of the passions.
