The saṁsāra means repetition of different bodies. That is called saṁsāra.
Prabhupāda: Because people have no knowledge about the next life, they are not interested with the spiritual education. That is the difficulty. They are not at all interested. Why people do not come here? They think that "These people will say that there is life after death, and if you do not do nicely, you will have to suffer. All this nonsense we have to hear, utopian." They are not interested. They are so dull. The facts... Kṛṣṇa is giving example. Dehino 'smin yathā dehe kaumāram... (BG 2.13). As you are changing your body... We have changed, every one of us, we have changed body. I was a baby. I was a child. I was a boy. I was young man. Now I have got a different body. Where have those bodies gone? They have no brain to think. I had all these bodies—that's a fact. And they are not existing now, that's a fact. And still I say, "There is no other body after death." What is the reason? What is the logic? How simple logic is given by... Not ordinary person, Kṛṣṇa, the Supreme Personality of Godhead, says that "As you have changed so many bodies, passed through so many bodies..." Every... Medical science says every minute we are changing body. That's a fact.
Just like the other day, Dr. P. Bannerjee came. That girl I saw changing from ten, twelve years ago. In 1955 I saw that girl, 1955. How many years ago?
Dhanañjaya: Nineteen years.
Prabhupāda: So that girl has grown up now nineteen years. At that time she was on the lap of her mother. So I said, "Oh, your daughter has grown up so much." She has changed so many bodies. But that body which I saw in 1955, that does not exist. Where is the illogical? That body is not existing, but the girl is there, and mother, father, "Yes, yes, she is my daughter, that daughter which you saw so little." The body has changed so many times.
So similarly, when I shall give up this body, I must have another body. And Kṛṣṇa says tathā dehāntara-prāptiḥ (BG 2.13). This is called saṁsāra. The saṁsāra means repetition of different bodies. That is called saṁsāra. Here, saṁsāriṇāṁ karuṇayā. Therefore this Kṛṣṇa consciousness movement is to be compassionate to these rascals who are in the cycle of changing body after body. It is a great movement. Everyone, all over the world, they are thinking there is no life after death. But that is not the fact. The fact is as you have changed so many bodies in this life, you have to change this body, you have to accept another body. It is a great dangerous position.
