What is LIGHT?

the Shabbos candles represent warmth and Light light is intangible so it's not a material thing it's a it's an abstraction you think about light you have a room that's dark and you can't see what's in the room and then you turn on the lights you say ah there's a beautiful banquet here well the banquet was there before the lights were turned on so turning on the lights doesn't actually put anything new in the room but it allows you to see it to appreciate it so it's intangible but uh it enhances our experience of all the tangible things that that's light
