Those, however, who saw that one cannot attain wisdom and perennial intellectual life, unless it be given through the gift of grace, and that the goodness of the Almighty God is so great that He hears those who invoke His name, and they gain salvation, became humble, acknowledging that they are ignorant, and directed their life as the life of one desiring eternal wisdom. And that is the life of the virtuous, who proceed in the desire for the other life, which is commended by the saints.

You are therefore able to run on this path, on which God is found above all vision, hearing, taste, touch, smell, speech, sense, rationality, and intellect.

Life and perfection, joy and repose and whatever all the senses desire, lie in the distinguishing spirit, and from it they have everything that they have.

In humility alone lies true greatness, and knowledge and wisdom are profitable only in so far as our lives are governed by them.
