The more real a thing is the less you can see it.  After you reach the level where you see all those things which are not to be seen, then you open your eyes and everything is clear to you, and it feels like you saw it all the time. To love someone is the deepest thing in the world, but you can’t prove it. You can’t put your finger on it, but it’s the most real thing in the world.

G-d is the most, utmost real thing in the world, and you can’t see Him, but after you don’t see Him, you see Him. Then you can see Him everywhere, in every flower, in every cloud, in every little stone, in every candle. When we say the Shema, G-d is One, we close our eyes, because first we don’t see G-d, we’re blind, we just believe, but then we open our eyes and it is so clear, He’s always there. ~ R’ Shlomo Carlebach zt”l
