Core Insight:
According to Osho, there is no real difference in essence: every ego is a nonentity born of unawareness. The normal ego is gross and visible - ambition for money, power, status - so it is easier to spot and drop. The spiritual ego is subtler and sanctified - virtue, holiness, powers - thus more poisonous, because it masquerades as nectar. Only bringing awareness (light) dissolves both.
