A brahmana, if he thinks that "Now I have brahminical qualifications, I am now educated, I am very cleansed, I am very controlled" - these things are brahmana qualification - "I know what is what," jnanam vijnanam, but he does not try for becoming immortal, then that kind of thinking is also bondage, that "I am this, I am that." Even though he is very learned, sattva samo damas titiksa suci, all these good qualities are there. But if he does not try to be, go further ahead, how to become immortal, so this type of fine entanglement is also entanglement. And those who are passionate, they are thinking, "I am so rich, I am so powerful, I have got so many nice business, bank balance, I have got my big family, nice wife." These are passion conception of life. So they are certainly bound up. And those who are ignorant, means one does not know what is the value of life, lying down anywhere, lazy, sleeping, unclean, do not know the value of life, they are in ignorance. They are very firmly bound up.
