At end of the narrator has an epiphany. How would you describe it?

The narrator's epiphany at the end of "Cathedral" comes with his ability to 'see' outside of himself, to imagine himself as part of something bigger. The irony is that he is taught to 'see' by a blind man, and he 'sees' only through refusing to open his eyes and behold the drawing he has made. The narrator's attitudes about sight at the beginning of the story exhibit his close-mindedness: he judges Robert for blindness, even though he himself is 'blind' to the truth of what blindness is (he admits he only knows it through TV). What he learns about sight is that it can be limiting when turned only to the particulars of one's own life, instead of directed outwards to how we are all connected to something greater.
