So when one comes out of this gross ignorance, how to get out of this bhava-sāgara . . . just like if you are thrown into the water of sea, you may be very expert swimmer, but you don't like to remain there. You want to come out. Similarly, although we may be very expert in changing our body, but still, at the time of death, we don't like it. Nobody likes to die. But he . . . nobody thinks how to stop this death. In the Bhagavad-gītā it is said, na hanyate hanyamāne śarīre (BG 2.20). By the destruction of this body, the soul is not dead. It is living. So this is called self-realization. One must be sober to think over that, "If I am eternal, if I do not die after the destruction of this body, and I do not like to die, how to stop it?" This is intelligence: how to stop the repetition of birth and death.
But the human civilization, the so-called human being has become so much degraded, they have no brain even to think over these matters, that how to stop this repetition or if there is any means to stop this repetition of birth and death. They do not . . . they have no knowledge. Still they are going on as human being. They're like animals. Even big, big professors in Europe, they say: "Swāmījī, after death, everything is finished." You see. Tathā dehāntara-prāptir dhīras tatra na muhyati (BG 2.13). Even these plain words, the first instruction of Bhagavad-gītā, they do not understand. Not only they. Here, also, so many politicians, so many rascals, they take Bhagavad-gītā, but they do not understand. They're busy with politics.
