According to Osho, 'inferiority complex' is psychobabble: the real issue is the ego, which exists only through comparison. When you compare, you oscillate between feeling inferior and superior; without comparison, ego dissolves and the problem vanishes. Like trees, simply be; enjoy what is without measuring yourself against others—then no inferiority exists.
There’s no special “inferiority bug” in you; you only feel small when you compare—stop comparing and the feeling goes away.
