According to Osho, there is no difference: “going within” and “going nowhere” are the same realization. He favors “nowhere” because “within” creates a false inside/outside split. Going nowhere means going not—dropping desire, motive, and movement so time falls away and only this moment remains. Then action, if any, happens from joy, not seeking; don’t be trapped by words.
It just means stop chasing anything and be fully here—inside and outside are one.
