This material world is a place for suffering, which is due to the misdeeds of the inhabitants, the conditioned souls themselves. The sufferings are not extraneously imposed upon them; rather, the conditioned souls create their own suffering by their own acts. In the forest, fire takes place automatically. It is not that someone has to go there and set a fire; because of friction among various trees, fire occurs automatically. When there is too much heat from the forest fire of this material world, the demigods, including Brahmā himself, being harassed, approach the Supreme Lord, the Supreme Personality of Godhead, and appeal to Him to alleviate the condition. Then the Supreme Personality of Godhead descends. In other words, when the demigods become distressed by the sufferings of the conditioned souls, they approach the Lord to remedy the suffering, and the Personality of Godhead descends. When the Lord descends, all the demigods become enlivened. Therefore Kardama Muni said, “After many, many years of human suffering, all the demigods are now satisfied because Kapiladeva, the incarnation of Godhead, has appeared.”
