According to Osho, people hate being criticized because the ego is a fragile patchwork of others' opinions; any blame threatens the self-image it has stitched together, so it resists and retaliates. We enjoy criticizing because trading in opinions props up the same ego by feeling superior. Freedom comes by dropping dependence on praise or blame and knowing oneself directly through awareness.
Your pretend self is built from what people say, so criticism hurts and judging others feels good; instead, trust your own clear seeing.
