     "In the <i>Vedas </i>the Supreme Lord is accepted as the purest of the pure. One who understands that Kṛṣṇa is the purest of the pure can become purified from all sinful activities. One cannot be disinfected from sinful activities unless he surrenders unto the Supreme Lord. Arjuna's acceptance of Kṛṣṇa as the supreme pure complies with the injunctions of Vedic literature. This is also confirmed by great personalities, of whom Nārada is the chief.",
     "Kṛṣṇa is the Supreme Personality of Godhead, and one should always meditate upon Him and enjoy one's transcendental relationship with Him. He is the supreme existence. He is free from bodily needs, birth and death. Not only does Arjuna confirm this, but all the Vedic literatures. the <i>Purāṇas </i>and histories. In all Vedic literatures Kṛṣṇa is thus described, and the Supreme Lord Himself also says in the Fourth Chapter, \"Although I am unborn, I appear on this earth to establish religious principles.\" He is the supreme origin; He has no cause, for He is the cause of all causes, and everything is emanating from Him. This perfect knowledge can be had by the grace of the Supreme Lord.",
     "Here Arjuna expresses himself through the grace of Kṛṣṇa. If we want to understand <i>Bhagavad-gītā, </i>we should accept the statements in these two verses. This is called the <i>paramparā </i>system, acceptance of the disciplic succession. Unless one is in the disciplic succession, he cannot understand <i>Bhagavad-gītā. </i>It is not possible by so-called academic education. Unfortunately those proud of their academic education, despite so much evidence in Vedic literatures, stick to their obstinate conviction that Kṛṣṇa is an ordinary person."
