According to Osho, witnessing is not a mental faculty or act of mind; thinking is the mind. Witnessing is the background consciousness—your innate nature—that shines only when thinking ceases. You cannot think and witness simultaneously. It appears in the silent gaps between thoughts and is unveiled by meditation, which slows minding. Thought is acquired and conditioned; witnessing is original, unconditioned awareness—the no-mind of the enlightened.
Witnessing isn’t thinking; it’s the quiet awareness that shows up when your thoughts pause.
