Oh, miserable is the fortune of our life, which is lived in such great peril and wherein it is so difficult to find the truth! For that which is most clear and true is to us most dark and doubtful; wherefore, though it is the thing that is most needful for us, we flee from it. And that which gives the greatest light and satisfaction to our eyes we embrace and pursue, though it be the worst thing for us, and make us fall at every step. In what peril and fear does man live, since the very natural light of his eyes by which he has to guide himself is the first light that dazzles him and leads him astray on his road to God! And if he is to know with certainty by what road he travels, he must perforce keep his eyes closed and walk in darkness, that he may be secure from the enemies who inhabit his own house—that is, his senses and faculties.
