According to Osho, witnessing is the transcendental awareness beyond all mental parts—the watcher on the hill—never any thought, feeling, or observer you can notice. As one part of mind watches another, the real you is whoever knows both; if a third appears, you’re the fourth. The criterion: whatever you can watch, you are not. Witnessing is this ever-transcending presence.
You’re not any thought or even the thinker you notice—you are the quiet space that keeps stepping back, always beyond whatever shows up in your mind.
