Bhagavad-gita As It Is
BG Chapters 7 - 12
BG 7.15, Purport:
The last class of duṣkṛtī is called āsuraṁ bhāvam āśritāḥ, or those of demonic principles. This class is openly atheistic. Some of them argue that the Supreme Lord can never descend upon this material world, but they are unable to give any tangible reasons as to why not. There are others who make Him subordinate to the impersonal feature, although the opposite is declared in the Gītā. Envious of the Supreme Personality of Godhead, the atheist will present a number of illicit incarnations manufactured in the factory of his brain. Such persons, whose very principle of life is to decry the Personality of Godhead, cannot surrender unto the lotus feet of Śrī Kṛṣṇa.
