According to Osho, only the witness—the pure, changeless consciousness that observes thoughts, dreams, sensations, and the world—is not illusion. All objects and experiences are temporarily true and thus illusory; they come and go. By shifting attention from the seen to the seer, you enter the non-illusory, eternal awareness that remains untouched by change.
The only thing that isn’t a passing dream is the quiet awareness inside you that notices everything come and go.
