Kṛṣṇadāsa: But what of our efforts to conquer cancer and tuberculosis?
Prabhupāda: No. Because we are conquering to. . . We are trying to avoid death. Then it is. . . Everything is cured. Cancer, cancer's father, grandfather—everything is cured. So we are trying for that. Tyaktvā dehaṁ punar janma naiti (BG 4.9). That is Kṛṣṇa consciousness, that "If you simply understand Me. . ." Janma karma ca divyaṁ me yo jānāti tattvataḥ. Simply if you understand what is Kṛṣṇa, why He comes, what is the purpose, then you become conqueror over death. That is our philosophy. Simply by understanding Kṛṣṇa. That is our progress, how much we have understood Kṛṣṇa. And when one understands fully Kṛṣṇa—fully it is not possible; at least partially—he is conquering over death. Tyaktvā dehaṁ punar janma naiti. That is real human life, how to conquer over death. Aihiṣṭhaṁ yat tat punar-janma-jāyāya. All the great sages and big, big kings, they left everything, went to the forest for austerity, penance. Why? To conquer over death. That is the mission. That. . . Everyone can do that, human life. And that is plainly explained in the Bhagavad-gītā, "Simply try to understand Me and you conquer over death." Simple thing.
