Conclusion:
When Krsna speaks of destroying and wiping out the world, He is talking about the destruction of the illusory physical and material world. He is the destroyer of fantasies, He is the destroyer of identities, He is the destroyer of egos, and He is the destroyer of all that is unreal. It is important to understand what Krsna means in these words. As the supreme consciousness, He too is the energy of Siva, the Rejuvenator. Siva is not the Destroyer as He is made out to be. He recreates by destroying. There can be no life without death. Krsna is the source of all beings, the creator of Brahma, who in turn created Prajapati, from whom all beings originated. He is the elements of nature, he extends everywhere and there is no place where He is not present
