From Vedic instructions we understand that this material world is created by the glance of the Supreme personality of Godhead (sa aiksata, sa asrjata). The Supreme personality of Godhead glanced over the mahat-tattva, or the total material energy, and when it was agitated, everything came into existence. Western philosophers sometimes think that the original cause of creation was a chunk that exploded. If one thinks of this chunk as the total material energy, the mahat-tattva, one can understand that the chunk was agitated by the glance of the Lord, and thus the Lord’s glance is the original cause of material creation.
