Prabhupāda: This attachment increases. The material attachment. The material attachment means "I am this body, and because I have got this body in a particular place, that is my country." And that is going on. "I am American," "I am Indian," "I am German," "I am this," "I am that," this bodily... "This is my country. I shall sacrifice everything for my country, society." So in this way the illusion becomes increased. So under this illusion, when he dies he gets another body. That may be a superior body or inferior body according to his karma. So if he gets superior body, then that is also entanglement. Even if he goes to the heavenly planet, that is entanglement. And if he becomes cats and dogs, then his life's lost. A tree. There is every chance. So this science is not known in the world, that how the soul is transmigrating from one body to another and how he's being entrapped in different types of body. This science is unknown.
