The ego is that part of the self that wants to be significant, central, and important. It is very self-protective by its very nature. It must eliminate the negative to succeed. (Jesus would call it the “actor” in Matthew 23, usually translated from the Greek as “hypocrite”.)
The shadow is that part of the self that we don’t want to see, that we’re afraid of and we don’t want others to see either. If our “actor” is well-defended and in denial, the shadow is always hated and projected elsewhere (we tend to hate our own faults in OTHER people!). One point here is crucial: The shadow self is not of itself evil; it just allows you to do evil without recognizing it as evil! That is why Jesus criticizes hypocrisy more than anything else. He does not hate sinners at all, but only people who pretend they are not sinners!
Jesus’ phrase for the denied shadow is “the plank in your own eye,” which you invariably see as the “splinter in your brother’s eye.” Jesus’ advice is absolutely perfect. “Take the plank out of your own eye, and then you will see clearly enough to take the splinter out of your brother’s eye” (Matthew 7:4-5).
