Pradyumna: "We prepare our next life by our actual activities in this present life. A living entity is offered a particular type of body as a result of his action in the present body."
Prabhupāda: Yes. Karmaṇā daiva-netreṇa jantor deha upapattaye (SB 3.31.1). Our next life means according to the karma, activities, in this life. They're judged at the point of death. The, our activities are judged and then we are given opportunity by the laws of nature to be carried in another mother's womb to get another gross body. We have got two kinds of bodies, the gross body and the subtle body. When this gross body is stopped working, the subtle body works. We have got experience every night. When you are lying down on bed, you are dreaming. You have gone somewhere else from your room and you are acting. That means the subtle body is acting. Similarly, when this body's stopped, nobody works, no more working, or the machine is broken, then, at that time, the subtle body carries you to another machine. This body is machine. Yantrārūḍhāni māyayā (BG 18.61). This is stated in the Bhagavad-gītā. This is yantra. So just like your car, you are driving one car, the car is stopped for some reason. It is no more working. Then what do you do? You get down. You get another car. Similarly, when this body's not working, then you give up this body; you take another body.
