Creation of world is an imagination of the mind. This delusion of the world is enacted by the mind and the mind alone. Mind is the world. The mind manifests itself as the external world. This universe is nothing but a mode of the mind, self-evolved from Brahman (Soul Consciousness), the cause of the universe. All the universes which appear only through Mind are no other than its modes. The mind is subjectively consciousness and objectively it is this universe. Hence, this all-pervading world is nothing but consciousness itself!
