You ever notice how once you hear about something you start seeing it all over? Lots of times we see things without taking it in or noticing it, because it’s not on our mind. Once we hear about it, and it’s on our mind, then we pay more attention and see it more often.
Something to say:
You shall not go explore after your hearts and after your eyes (15:39).
Rashi explains: the eye sees, the heart desires, and the body commits the sin. The Toldos Ephraim points out that Rashi should have followed the sequence of the verse; the heart desires and the eye sees. However, he answers that what the heart does not desire, the eye does not see at all.
We see what we want to see. So someone who has good on their mind will see the good. Someone who thinks of evil will see the evil. So lets keep our hearts and mind on the good, and we will see good.
