So here it is said, śrī-bhagavān uvāca. The most powerful authority is speaking. Therefore, whatever He says, it is to be taken as truth. In our this conditional life, just like we are living under material condition, we have got four defects: we commit mistake, we are illusioned, and we want to cheat also, and our senses are imperfect. So knowledge received from a person who is infected with four kinds of deficiencies is not perfect. So when you receive knowledge from a person who is transcendental to all these four kinds of defects, that is perfect knowledge. Modern scientists, they theorize that "It may be like this. It may be like that," but that is not perfect knowledge. So if you speculate with your imperfect senses, what is the value of that knowledge? It may be, I mean to say, partial knowledge, but that is not perfect knowledge. Therefore our process of receiving knowledge is to receive it from the perfect person. And therefore we are receiving knowledge from Kṛṣṇa, Bhagavān, the most perfect, and therefore our knowledge is perfect. Just like a child. He may be imperfect, but if his father says, "My dear child, this is called spectacle," so if the child speaks, "This is spectacle," that knowledge is perfect. Because the child does not make research to find out knowledge. He asks his father or mother, "What is this, Daddy? What is this, Mother?" And the mother says, "My dear child, this is this." Another example can be given that if a child does not, in childhood, he does not know who is his father, then he cannot make any research work. If he makes research work to find out his father, he'll never find out his father. But if he asks his mother, "Who is my father?" and the mother says, "He is your father," that is perfect. Therefore knowledge, knowledge of God, who is beyond your sense perception, how can you know? Therefore you have to know from God Himself or His representative.
So here Kṛṣṇa, the Supreme Personality of Godhead, is speaking, and that is the final authority. He says to Arjuna as follows. He says, aśocyān anvaśocas tvaṁ prajñā-vādāṁś ca bhāṣase: (BG 2.11) "My dear Arjuna, you are talking like very learned scholar, but you are lamenting on a subject matter which you should not do." Gatāsūn agatāsūṁś ca nānuśocanti paṇḍitāḥ. Gatāsūn means this body. When it is dead or when it is alive, bodily conception of life is foolishness. So no learned man takes serious consideration of the body. Therefore in the Vedic literature it is said that "One who is in the bodily concept of life, he is nothing more than an animal." Therefore at the present moment, without knowledge of the self, the whole world is going on under the bodily concept of life. The bodily concept of life is there amongst the animals. The cats and dogs, they are very proud of becoming a big cat or big dog. Similarly, if a man also becomes similarly proud that "I am big American," "big German," "big," what is the difference? But that is actually going on, and therefore they are fighting like cats and dogs.
So we shall discuss more tomorrow.
