So we are beginning today speaking on Bhagavad-gītā, the preliminary scientific study of this science of Godhead. Bhagavad-gītā means Bhagavān, the Supreme Personality of Godhead. Bhagavān means the Supreme Personality of Godhead. Bhaga, we generally know, bhāgya, opulence, fortune, a man is called bhāgyavān. This bhāgyavān word comes from the word bhaga, Bhagavān. Bhaga means opulence, six kinds of opulences: wealth, strength, influence, education, wisdom, beauty, and renunciation. These are opulences. If a man is wealthy, he's attractive. He attracts. Any man, very wealthy, he attracts. Similarly, if he's very strong, if he's very influential, if he's very learned, wise, if he's very beautiful... He or she, it doesn't matter. Or if he's a great renouncer, one who has renounced everything for public benefit, naturally we have got attraction. So in this material world we find some wealthy man, some rich man, some strong man, some beautiful man, some wise man, one renounced man, but they are only fragmental. Fragmental, very small quantity. Any man... You can take a rich man. He may be very rich man, but, in comparison to the other persons in the material world, but nobody can claim that "I am the richest man." No. That is not possible. Nobody can claim. "I am the wisest man," nobody can claim. "I am the strongest man," that is also, nobody can claim. However one strong may be, he is under the rules and regulation and material nature. He cannot go beyond that. Therefore you cannot find Bhagavān, or the Supreme Person, possessing all these opulences. That is not possible.
But here it is said, bhagavān uvāca. That means He's the richest, He's the strongest, He's the most beautiful, the wisest, and the most renounced order of life. Kṛṣṇa. When He was present in this material world, on this globe, He proved by His actions. So far His richness is concerned,... At this age, in this age, at the present moment, if a person can provide his family nicely, nice apartment or nice house, good dress, good food, he's considered to be very successful man. Because in this age... It is said in the śāstra, dākṣyaṁ kuṭumba-bharaṇam. Kuṭumba. Kuṭumba means family. If one can provide his family very comfortably, he is considered as very expert. But the family maintenance is done by the cats and dogs also. They also maintain their family, their wife, children, very nicely, according to their standard. But this age is so fallen that if one, even one is not married, the preliminary necessities of life, eating, sleeping, sex life and protection from fear... These are the preliminary necessities. So the age is so fallen that people have no eating substance even. We know, everyone, how things are going on. People are hungry, no eating substance. And what to say of sleeping? Or what to speak of...? Nobody's married timely, either boys or girls. And nobody's secure. Nobody knows what will happen next moment. This is called Kali-yuga.
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 (is) 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. Those who are infected with these defects, they cannot give you perfect knowledge. That is not possible. Imperfectness of senses—how he can gather perfect knowledge? They can simply say, "Perhaps," "It may be," "Most probably." That's all. Theories. Nobody can say, "It is like this." Just like in the Vedas it is said how many different varieties of lives are there. Jalajā nava-lakṣāṇi sthāvarā lakṣa-viṁśati, kṛmayo rudra-saṅkhyakāḥ. Exact number, that so many varieties of lives are there. Nine hundred thousand species life in the water. Jalajā nava-lakṣāṇi sthāvarā lakṣa-viṁśati. Two million varieties of trees, plants, like that. Kṛmayo rudra-saṅkhyakāḥ. Eleven lakhs varieties of insects. Pakṣiṇāṁ daśa-lakṣaṇam. There are ten, one million types of birds. Similarly, three million types of animals, and four hundred thousand different types of humankind. Everything is exactly calculated. That is called Vedic knowledge. Because it is... How the perfection of knowledge comes? Here it is said, imaṁ vivasvate yogaṁ proktavān aham (BG 4.1). Kṛṣṇa says. Aham avyayam. The knowledge is perfect. Avyayam. Avyayam means "that cannot be diverse or deviated." Perfect. Avyayam. Without any deviation. Therefore if you want to know perfect knowledge, then you have to hear from Kṛṣṇa.
