"When you CORRECT a brother, you are telling him that he is WRONG. He may be making no sense at the time, and it is certain that if he is speaking from the ego, he WILL be making no sense, but your task is still to tell him HE IS RIGHT. You do not tell him this verbally if he is SPEAKING foolishly, because he needs correction AT ANOTHER LEVEL, since his error IS at another level. HE is still right, because he is a Son of God. His ego is ALWAYS wrong, no matter WHAT it says or does."
When you see a person acting egoically, you will think this is all they are. Whatever they say and do, you point your finger at "that" and consider it the whole person. This is why its incredibly easy to judge and condemn people for their egoic behaviors. As if what you see them doing is what thy are in truth.
But what this really means is you are blinded by perception of form and lack vision, so you are not seeing THROUGH and BEYOND their ego. The fact is that the person simultaneously is a perfect soul, and yet they also have egoic beliefs in their mind. Kind of like having two selves.
If you only see the ego in them and do no look past it ("to forgive is to overlook"), you become blinded by it and do not see their real self. You then hold their ego against them as if that is all they are. In effect, there is more to people than meets the eye.
Jesus is saying we should try not to be deceived by people's mistakes, and recognize it as a call for love. To look past appearances to the holy child of God that everyone is in truth. If you could see past their ego to their holiness, you would recognize their ego as just mistaken, instead of sinful.
Remember everyone here has two selves so when you take everything people say at face value you're not being forgiving. You have to look deeper past the surface. Give your brother due credit and love or still being a perfect soul. Recognize his mistakes as only that, and hold nothing not of God against him. To fixate on a person's ego is to be believe the forms of error.
"To forgive is to OVERLOOK. Look, then, BEYOND error, and do not let your perception rest UPON it, for you will believe what your perception HOLDS. Accept as true only what your brother IS, if you would know yourself. Perceive what he is NOT, and you CANNOT know what you are, BECAUSE you see HIM falsely. Remember always that your identity is shared, and that its sharing IS its reality."
"See how the body's eyes rest on externals, and CANNOT go beyond. Watch how they STOP at nothingness, unable to go BEYOND the form to meaning."
"Before a holy relationship, there IS no sin. The FORM of error is no longer seen. And reason, joined with love, looks quietly on ALL confusion, observing merely, "this was a mistake." And then the same Atonement YOU accepted in YOUR relationship, CORRECTS the error, and lays a part of Heaven in its place. How blessed are you, who let this gift be given! Each part of Heaven that you bring, is given YOU. And every empty place in Heaven that you fill again with the Eternal Light YOU bring, shines now on YOU. The means of sinlessness can know no fear, because they carry ONLY love with them."
