I believe that the old man did indeed have far too narrow an idea of what a vision might be. He may, so to speak, have been too dazzled by the great light of his experience to realize that an impressive sun shines on us all. Perhaps that is the one thing I wish to tell you. Sometimes the visionary aspect of any particular day comes to you in the memory of it, or it opens to you over time.
