Bhagavad-gita As It Is
BG Chapters 1 - 6
BG 4.4, Purport: The devotees will always worship such authoritative statements of Kṛṣṇa because they are always eager to know more and more about Him. The atheists, who consider Kṛṣṇa an ordinary man, may in this way come to know that Kṛṣṇa is superhuman, that He is sac-cid-ānanda-vigraha [Bs. 5.1]—the eternal form of bliss and knowledge—that He is transcendental, and that He is above the domination of the modes of material nature and above the influence of time and space. A devotee of Kṛṣṇa, like Arjuna, is undoubtedly above any misunderstanding of the transcendental position of Kṛṣṇa. Arjuna's putting this question before the Lord is simply an attempt by the devotee to defy the atheistic attitude of persons who consider Kṛṣṇa to be an ordinary human being, subject to the modes of material nature.
CC Adi 17.257, Purport: In the Bhagavad-gītā it is said, māyayāpahṛta-jñānā āsuraṁ bhāvam āśritāḥ: when one becomes inimical to the Supreme Personality of Godhead, adopting an atheistic attitude (āsuraṁ bhāvam), even if one is a learned scholar the essence of knowledge does not become manifested in him; in other words, the essence of his knowledge is stolen by the illusory energy of the Lord. In this connection Śrī Bhaktisiddhānta Sarasvatī Ṭhākura quotes a mantra from the Śvetāśvatara Upaniṣad (6.23):
Bhagavad-gita As It Is Lectures
Lecture on BG 7.7 -- Vrndavana, August 13, 1974: The controversy about the Absolute Truth, whether the Absolute Truth is form or formless... There are many philosophers. They, some of them are impersonalists, and some of them are personalists. They... In India the impersonalists are known as Māyāvādī, and the personalists, they are known as Vaiṣṇavas. So here the decision is given by Kṛṣṇa Himself, the Supreme Personality of Godhead. Kṛṣṇa means Bhagavān. Kṛṣṇas tu bhagavān svayam [SB 1.3.28]. This is the conclusion of Śrīmad-Bhāgavatam. And in the Ṛg Veda also it is said, tad viṣṇoḥ paramaṁ padam: "Viṣṇu is the Supreme"; sadā paśyanti sūrayaḥ, "Those who are demigods, or advanced in spiritual knowledge, they always look after the lotus feet of Viṣṇu." But the demons, they do not know that the Viṣṇu is the Supreme Personality of Godhead, Absolute Truth. They cannot. Because they have taken the atheistic attitude, they cannot understand the Absolute Truth as the Supreme Person.
Arrival Addresses and Talks
Arrival Address -- Paris, June 8, 1974: There are many classes of men, they have been classified as the duṣkṛtina, mūḍha, narādhama, māyayāpahṛta-jñānā, and all of them are based on the atheistic theory "There is no God, I am God." Asuri bhāvam, asura. Asura means they defy God, "I am God. Who is God?" Just like Hiraṇyakaśipu and his son, Prahlāda Mahārāja. Prahlada Mahārāja is devotee of Lord Kṛṣṇa, and Hiraṇyakaśipu would not accept. "Who is God? I am God." This is atheistic attitude. So the atheist are divided into four classes.
Conversations and Morning Walks
1976 Conversations and Morning Walks
Evening Darsana -- July 7, 1976, Washington, D.C.: Prabhupāda: The human life is meant for this purpose, to understand God. But he does not. Therefore we say narādhama, lowest of mankind. "But he is very educated." māyayāpahṛta-jñāna. He is so-called educated. Actually, he is not educated, because he does not know what is God. Māyayāpahṛta-jñānā āsuraṁ bhāvam āśritāḥ. The basic principle is atheistic attitude. So these class of men will never offer obeisances or surrender to God.
