tvam dharmas tvam rtam satyam

tvam loka-palah sarvatma

Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O Sudarsana wheel, you are religion, you are truth, you are encouraging statements, you are sacrifice, and you are the enjoyer of the fruits of sacrifice. You are the maintainer of the entire universe, and you are the supreme transcendental prowess in the hands of the Supreme Personality of Godhead. You are the original vision of the Lord, and therefore you are known as Sudarsana. Everything has been created by your activities, and therefore you are all-pervading.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The word sudarsana means “auspicious vision.” 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.
