The first step is to sever the right eye of the enemy from his or her body and put it somewhere. Of course, this is just a visualization since we cannot possibly gouge out the right eye of a person. Next, visualize removing the left eye from the body and putting it in a certain place, then the ear, nose, tongue, skin, bone, muscle, hair, blood, and different organs; remove whatever can be removed and place it in front of yourself.

Then contemplate: normally I have absolutely no control over the deep hatred I feel for this person. But what among these things is the object of my hatred? Is it the eye, ear, nose, muscle, bone, or blood?

The result of this kind of investigation is that the enemy cannot be found. If the person doesn’t even exist, why would we hold feelings of anger toward his muscle, bone, and so forth? These component parts, the muscle, bone, etc., have never hurt me, not in this life nor will they in the next. Why should I bear grudge if they have never bothered me?
