A good practice for this phase of learning is to notice when you have constructed an identity for yourself or another. What was the purpose of this decision about who someone is or isn’t? Was there a trajectory that would end in a judgment of superiority or inferiority?
You are able to watch the thoughts attempting to piece together a judgment before the emotions come. See them. Laugh. Breathe.
Is there an identity beyond comparison?
Notice when you have begun to use a concept of an ideal to form a judgment. Notice how several thoughts chain themselves together in rapid succession, form a declarative judgment, and always end up separating one person from another. The pain you feel in the wake of that is the pain of separation, of separate identity, of following the guidance of that which would perceive a world of opposition and fear (pushing against to reinforce separation).
Notice what happens when you have declared a superiority. You have separated the wholeness out into components and believed in disharmony, in things not working, in disordered stasis instead of the Truth of the Whole.
Remember the Truth of the Whole. Allow that to be reflected in the world you see.
