The ego makes no sense.

If you point out the errors of your brother’s ego you must be seeing through yours, because the Holy Spirit does not perceive his errors. This must be true, since there is no communication between the ego and the Holy Spirit. The ego makes no sense, and the Holy Spirit does not attempt to understand anything that arises from it. Since He does not understand it, He does not judge it, knowing that nothing the ego makes means anything.
