“ When you feel angry or frustrated at a brother for using a particular defense -- being controlling or whatever it is -- you are failing to forgive yourself for the very same attempt; you still believe that the defense has a reality. You are seeing it out there but when you start to pull it back to your mind, you start to see the control in yourself. The guilt from transferring it from one seeming person/body to another seeming person/body is enormous. Instead of blaming your brother, the blame gets turned onto your own seeming body, but it is still the same error. We have to see that I am mind; this identity that I took off of my brother but still saw in myself is also just a construct in my mind. Otherwise, what good is the transfer? ”
