When you look at something, how much of what you see is really your mind hard at work vs what you actually see? Just like your mind can fill in the gaps and interpret sound, your mind also fills in the gaps with sight. Look closely at this collage of photos. After you are confused as to what you are looking at, stand across the room and look again. Surprise! Our minds pretty much make up a lot of stuff that we THINK we see. We would be wise to keep that in mind when we are certain of anything.
