For a mitzvah is a candle and Torah is light. (Proverbs 6:23) Every mitzvah shines its particular light into our world. And there will come a time when you will see that light with your eyes. Except the candles that are lit for Shabbat before sunset. They shine a light you can see right now. It may seem an ordinary light, just another flame. But there is nothing ordinary about it. You have ignited the darkness of our world and extracted its secret: That it too is light.
