Kali-yuga means mandāḥ sumanda-matayo manda-bhāgyā hy upadrutāḥ (SB 1.1.10). Prāyeṇālpāyuṣaḥ kalāv asmin yuge janāḥ. Asmin yuge, kali-yuge, alpa āyuṣaḥ, they are living very short time. The duration of life reducing. Anyone can know. His forefather, his grandfather, lived for, say, hundred years. His father lived for eighty years. And he's going to live for sixty years. In this way, the duration of life will be reduced up to twenty years. That is already foretold. If a man lives for twenty to thirty years, he will be considered very old man. That day is coming. Because how they will live? There is no eating, there is no sleeping. There is no fixture of this program. These are required. Annād bhavanti bhūtāni (BG 3.14). Simply by dry lecture, how they will feel happy? There must be sufficient food grains so that people may live happily, the animal may live happily. Especially in India you will see, no animal is fatty, either cat, dog or cow. They have no eating. So annād bhavanti bhūtāni. They must be given sufficient food, annād. Kṛṣṇa does not say that, "You fast and chant Hare Kṛṣṇa." He does not say. Kṛṣṇa is not so impractical. He says: "Eat very nicely, keep very nicely, and chant Hare Kṛṣṇa. Make your life successful." That is Hare Kṛṣṇa consciousness movement. Kṛṣṇa consciousness movement is not one-sided. It is all-embracing. Sarve sukhino bhavantu. Kṛṣṇa consciousness movement wants to see everyone happy. Without being happy, how you can remain peaceful? That is not possible.
Therefore, bhagavān uvāca. You take lessons from Bhagavān, the Supreme Personality of Godhead, perfect, all-perfect. What he will do by hearing this rascal or that rascal? Try to hear from the Supreme Personality without any fault, without any deviation. There are four kinds of defects in conditional life: to commit mistake, to be illusioned . . . bhrama, pramāda, vipra-lipsā. To cheat, propensity for cheating. And imperfection of senses. So we are all infected with these four deficiencies of life, material condition of life. Therefore mukta means one who is liberated from these defects.
