According to Osho, both self-remembering and witnessing reach the same goal—enlightenment—but their dynamics differ radically. Witnessing is simpler and safer because the ego has no foothold in it. Self-remembering is longer, harder, and dangerous; the ego easily masquerades as the self, strengthening itself. Therefore, only rare seekers succeed with self-remembering, and it requires the guidance of a rigorous master.
They’re two roads to the same place, but witnessing is the safe, straight path, while self-remembering is a tricky road where your pretend-self can fool you—so you’d need a skilled guide.
