Brahmā, it is I, the Personality of Godhead, who was existing before the creation, when there was nothing but Myself. Nor was there the material nature, the cause of this creation. That which you see now is also I, the Personality of Godhead, and after annihilation what remains will also be I, the Personality of Godhead.
