Lord Saṅkarṣaṇa is the ocean of unlimited spiritual qualities, and thus He is known as Anantadeva. He is nondifferent from the Supreme Personality of Godhead. For the welfare of all living entities within this material world, He resides in His abode, restraining His anger and intolerance.
Anantadeva’s main mission is to dissolve this material creation, but He checks His anger and intolerance. This material world is created to give the conditioned souls another chance to go back home, back to Godhead, but most of them do not take advantage of this facility. After the creation, they again exercise their old propensity for lording it over the material world. These activities of the conditioned souls anger Anantadeva, and He desires to destroy the entire material world. Yet, because He is the Supreme Personality of Godhead, He is kind toward us and checks His anger and intolerance. Only at certain times does He express His anger and destroy the material world.
