Lord Kṛṣṇa said,
- dehino 'smin yathā dehe
- kaumāraṁ yauvanaṁ jarā
- tathā dehāntara-prāptir
- dhīras tatra na muhyati
- (BG 2.13)
This is Sanskrit language. I'll explain it in English. He said that within this body there is soul, and the body is changing every moment, but the soul is there. He is giving example, just as a soul comes from the womb of his mother with a small body, and that small body changes—it becomes the body of a boy, it becomes the body of a youth, then it becomes the body of an old man, then it vanquishes... That we have to admit. We may say that the body is growing, but actually, the fact is, body is changing. It is medically admitted that we are changing our body every second. We are changing our blood corpuscles, and therefore a change of the body is taking place, and that is being manifested in a different shape only. Actually, we are changing every moment our body. So the ultimate change, when this body cannot be worked any more, just like a dress, when it is torn, when it is too old, you have to change it. Similarly, when this body becomes useless, no more, it cannot be pulled on any more, you take another body. Tathā dehāntara-prāptir. As we are, in our practical life, we are changing our body every moment, similarly, the last stage of changing this body is called death. Death means, according to Vedic literature, sleeping for seven months. Just as I give up this body, I have to enter into the womb of some kind of mother. These things are explained in the Vedic literatures. I am not manufacturing. That karmaṇā dehopapattaye. We are preparing our next life, next body rather... Life is continuing. I am eternal. Next body—according to my present one.
