According to Osho, no one began the universe: existence is beginningless and endless, autonomous, and not a creation. Invoking a creator only pushes the question back—who created the creator? The mind, limited to finite concepts, invents God for consolation; only going beyond mind and tasting inner eternity reveals that being and cosmos are uncreated, organic realities, not mechanisms manufactured by someone.
Nothing started everything—the universe has always been, and you can sense this by quieting the mind beyond ideas.
