You can stop your birth and death. And if you stop your birth and death, then you stop your disease and old age. That eternity—you are eternal. You get your eternal life. Na hanyate hanyamāne śarīre (BG 2.20). We eternal . . . even if we get this material body, even though we change this material body, just like I was a baby, you were a baby, but that body is no longer existing. I am in different body, still I am existing. Therefore, na hanyate hanyamāne śarīre (BG 2.20). Although the body has changed, I am not changed. This is my position. Therefore perfection of life is to keep oneself in his original, constitutional position, not to change body. But that is possible. How it is possible? Tyaktvā dehaṁ punar janma naiti mām eti kaunteya (BG 4.9). Everything is there. How it is possible?

If you want to go to the higher planetary system by pious activities, you can go there, yānti deva-vratā devān. You can go to the planet where Lord Brahmā lives or where Indra lives or Candra lives. The modern process, by taking a sputnik or jet, you can go to the moon planet. But that you can go. Whether you can go or not go, that is up to you. But you cannot stay there. That is not possible. If you want to stay there, then yānti deva-vratā devān. You have to prepare yourself by worshiping that particular deva or deity, demigod; then you will be admitted. Just like if you want to go to a foreign country you have to take the permission of the immigration department, visa, then you can go. If that law is there in this planet, why not for other planet?
