The Gemara in Taanit says that when you take large strides, you lose 1/500th of your eyesight, and commentaries bring down that the remedy for this each week is to look at the Shabbos Candles when reciting kiddush on Friday night.
A) I’ve heard a possible interpretation of this midrash to mean that when you move fast through life without taking the time to look around (aka when you take large strides), you’re missing out on things and therefore “lose your eyesight”. According to this interpretation, why is looking at the Shabbos candles a remedy for this issue of brushing through life without taking it all in? And further, what’s the significance of the number 500?
B) Anyone know of any better understandings of this midrash?
