“The Gemara asks a question, if a blind man should wear tzitzis on his garment. He has a four corner garment, does he need tzitzis? Because it says uri’isem oso, ‘you should see it’ and a blind man cannot see it. So maybe it’s patur from tzitzis. So the Gemara says, no that’s no reason because sha’ani tzitzis sh’yeshnah b’riah etzel acharim (Menachos 43a) other people should see his tzitzis. So a blind man should wear tzitzis not really for himself, (but) for other people to see. Now that’s a remarkable thing we are hearing now. It means the tzitzis that you are wearing are not only for you to see, it’s for me to see too. So let’s say a woman thinks I’m not wearing tzitzis so it doesn’t apply. No it applies to her too. As she sees her boys going around with tzitzis she should see the tzitzis uri’isem oso, you should see the tzitzis uzachartem, ‘you should remember’. And oso doesn’t mean only tzitzis, oso means you see Hashem when you see the tzitzis.”
