The whole universe is maintained by the integrating power of the Supreme Lord, who is known in that capacity by the name Sankarsana. The material scientists may have discovered the law of gravity, which maintains the integration of objects within the material energy, yet the master of all integration can create devastation by the disintegrating blazing fire emanating from His mouth. A description of this can be found in the Eleventh Chapter of Bhagavad-gita, wherein the universal form of the Lord is described. The master of integration is also the destroyer of this world by virtue of His disintegrating energy. Sankarsana is the master of integration and disintegration, whereas Pradyumna, another feature of Lord Vasudeva, is responsible for universal growth and maintenance. The word suksmaya is significant because within this gross material body there are subtle material bodiesnamely mind, intelligence and ego. The Lord in His different features (Vasudeva, Aniruddha, Pradyumna and Sankarsana) maintains both the gross and subtle material elements of this world. As mentioned in Bhagavad-gita, the gross material elements are earth, water, fire, air and ether, and the subtle material elements are mind, intelligence and ego. All of them are controlled by the Supreme Personality of Godhead as Vasudeva, Sankarsana, Pradyumna and Aniruddha, and this will be further explained in the following verse.
