Lecture on BG 4.13 -- Johannesburg, October 19, 1975:
Guest (4): Prabhupāda, is it true that can a human body takes a form of a human body in the next birth?
Prabhupāda: No. Kṛṣṇa doesn't say. Tathā dehāntara-prāptiḥ (BG 2.13). You will get another body, but that does not mean human body. That will depend on your price. Just like if I say, "When your coat is old and torn, you'll purchase another coat." So that another coat, what kind of coat, that will depend on your price, as you are able to pay. Similarly, your activities in this life will decide what body you are going to get next life.
Guest (4): Prabhupāda, that, perhaps, contradicts with the theory of reincarnation?
Prabhupāda: What is that incarnation theory? You are going to get another body. That is reincarnation. Now, what kind of body you are going to get, that will depend on your work. There are 8,400,000 different types and forms of body. So you are at liberty to work. Therefore the direction is there in the Bhagavad-gītā, "You work like this. Then you get the body like this." So this is risky life. Without knowing the law of God, without knowing how nature is working, how the living entity is getting different types of body, without this knowledge, if we simply keep ourself on the business of eating, sleeping, sex and defense like cats and dogs, this is very, very risky life.
So our Kṛṣṇa consciousness movement is trying to save the human society from this risky life and to understand what is God, how he can go back to home, how he can get eternal life. This is our business.
Puṣṭa-kṛṣṇa: Are there any other questions?
Prabhupāda: That's all right. Chant.
