According to Osho, Krishna was indeed a devotee—but not of any particular external deity. Devotion is an inner attitude, not allegiance to someone. Through such devotion, the world appears divine, and the seeker who begins as a devotee is fulfilled as God. Thus Krishna embodies both: devotion that reveals God everywhere and the realization of that divinity within.
Krishna wasn’t devoted to a separate god; his loving devotion made the whole world—and himself—shine as God.
