PURPORT

The words abhivyanag jagad idam refer to he who creates this cosmic manifestation. The original creator is the Supreme Personality of Godhead, Krsna (janmady asya yatah); Lord Brahma is the secondary creator. When Lord Brahma is empowered by Lord Krsna as the engineer to create the phenomenal world, he becomes the supremely powerful feature within this universe. The total material energy is created by Krsna, and later, taking advantage of all that has necessarily been created, Lord Brahma engineers the entire phenomenal universe. At the end of Lord Brahma's day, everything up to Svargaloka is inundated with water, and the next morning, when there is darkness in the universe, Brahma again brings the phenomenal manifestation into existence. Therefore he is described here as he who manifests this universe.
