You have to think how this body will be manufactured, but Kṛṣṇa is so intelligent, His potencies are so great, that simply He . . . "This soul should get such-and-such body"—immediately it is manufactured and comes out. This is Kṛṣṇa's intelligence. Parāsya śaktir vividhaiva śrūyate (Śvetāśvatara Upaniṣad 6.8, CC Madhya 13.65, purport). You cannot manufacture this. But under Kṛṣṇa's direction there are certain energies which can immediately manufacture.
But the rascal says: "Automatically it is coming." Not automatically. There is brain, there is energy, there is discretion, there is judgment. There is all these things. Then it will come out with another body. Not blindly. The rascals, they see, "It is coming out blindly." No.
How much the mechanism is there within the body that they are working so nicely? Two kinds of secretion mix, and immediately they get energy. The mother eating; from that eating the child is also eating, the intestine is connected . . . (indistinct) . . . how much mechanical arrangement is there? Can any medical science, any scientist connect . . . (indistinct) . . . even this is matter? Even this is matter, let them manufacture outside this body another body. No.
We . . . suppose we have to manufacture something, a small watch. That particular watch has to be manufactured. But Kṛṣṇa has created so nicely that two machines—one male machine, one female machine—and they're joining, and so many machines are coming out. Not that each and every particular machine body has to be tackled. Kṛṣṇa has made so nice arrangement, His intelligence is so sharp, the potency is there that one male machine, one female machine, and they are producing unlimited number of machines. You have to manufacture a machine, a car, in the factory in so many ways. This is Kṛṣṇa's intelligence. Parāsya śaktir vividhaiva śrūyate. How nice intelligence, how His energies are acting, so who can explain this? Therefore acintya. Acintya. Acintya means inconceivable.
