Vyāsadeva is the writer of Vedānta philosophy, and he has written a comment personally, so that in future, rascals may not misrepresent Vedānta. There are so many bhāṣyas, but that is not commentary. Real commentary . . . the author knows what he wants to speak. So Vedānta is the compilation by Vyāsadeva. So he knows what, what he wants to speak. What others have got the right? Just like Bhagavad-gītā. The purpose of Bhagavad-gītā is known by Kṛṣṇa. Why the rascals comment in different way? They may write their rascal philosophy, other. Why they touch Bhagavad-gītā and give different interpretation? They have no right. I have written a book; I have got my purpose. Why you should poke your nose and make it a different purpose? This is very mischievous rascaldom. So we want to stop this. We present Bhagavad-gītā as it is, as Kṛṣṇa says. We don't allow any rascal to comment upon Bhagavad-gītā in a different way. That is our Kṛṣṇa consciousness movement. This is very natural. If you have got a different type of philosophy, you can write. Why you should touch Bhagavad-gītā and misrepresent it? So because they are śūdras—their business is to cheat—they do that. But a brāhmaṇa will not do that. Yathānugītānām. Yathānugītānām. Brāhmaṇa means as it is, they will describe. That is brāhmaṇa. And if one has got some motive, that "Bhagavad-gītā is popular book. Let me utilize it and make my rascal philosophy popular . . ." This is going on. Big, big politician, big, big mental speculator . . . no. That is wrong. That is śūdra. A brāhmaṇa should present as it is. Yathānugītānām. This word is used.
So this dvijaḥ, brāhmaṇa . . . brāhmaṇa means one who has acquired these qualifications, satya śama damo titikṣa. The first qualification of brāhmaṇa is to become truthful. He'll never speak lies. That is the first qualification. Satya śama, then controlling the senses; dama, controlling the mind. Śama means controlling the mind, and dama is controlling the senses. Śama dama titikṣa (BG 18.42). Titikṣa means tolerance. Titikṣa ārjava, simplicity; and full knowledge, jñānam; vijñānam, practical. Simply theoretical knowledge, no practical application—he is not brāhmaṇa. Therefore Kṛṣṇa said, guṇa-karma. Only guṇa is not good. Guṇa and karma. Karma means some act.
