If we examine the function of judgment in personality, we see that it serves to reinforce our sense of self by separating us from that which we are judging. Judgment is one of the most powerful ways that human beings draw boundaries and cut themselves off from direct contact with their experience. When we judge ourselves, we create a state of internal war. Like war, judging is very expensive in the energy, time, and effort it consumes. Rather than expand us or liberate us, our judgments exhaust us and limit us.
The Essential self exercises discernment, notes differences, and makes decisions about what to do; by contrast, ego-based judgment always carries a certain negative emotional charge. Its primary function is not to discern but to create distance (boundary). The hallmark of judgment…is that it is divisive.
