Hayagrīva: Now the following quotes are taken from a, a much later book, one of the last books he wrote, called The Undiscovered Self. And it's very popular, and in it he discusses religion, in certain ways almost anticipates the Kṛṣṇa consciousness movement. At the beginning he defines the purpose of religion. He says, "The meaning and purpose of religion lie in the relationship of the individual to God, or to the path of salvation and liberation." And of the first instance he gives Christianity, Judaism, Islam, and the last instance he gives Buddhism. He says, "From this basic fact, that is the relationship of the individual to God, all ethics is derived, which, without the individual's responsibility before God, can be called nothing more than conventional morality."
Prabhupāda: Yes. Morality, as we understand from Bhagavad-gītā, that nobody can approach God without being purified of all sinful reaction. Yeṣām anta-gataṁ pāpaṁ janānāṁ puṇya-karmaṇām. A person who has finished all sinful activities, and simply standing on the platform of pious activities, they can understand what is God and be engaged in God's service. And another place it is said by Arjuna, paraṁ brahma paraṁ dhāma pavitraṁ paramaṁ bhavān: (BG 10.12) "You are the Supreme Personality of Godhead, param brahma." Every living being is Brahman, spiritual, but Kṛṣṇa is the Supreme Being; therefore He is paraṁ brahma, and the paraṁ dhāma, and the resort of everything, ultimate resort of everything, and pavitra, purified, there is no material contamination. So, what is this? What does he say in this?
