Nature's law is very, very strict. This life it is given, a chance. Nature gives a chance. Now you get this human form of life, advanced consciousness. Now you make further improvement. That is wanted. From here we can make further improvement. What is that further improvement? We can go to the better planets. There are many better planets. You can go there, heavenly planets. There you can live for ten thousands of years. Ten thousands of years, and that is also not our year. The higher planetary system, their one day—our six months. In that way you can live there for ten thousands of years. And the standard of living condition is thousand times better. Therefore it is called heavenly.
So if you like, you can go there. Ūrdhvaṁ gacchanti sattva-sthaḥ (BG 14.18). Yānti deva-vrataḥ devān (BG 9.25). Everything is explained. Or if you can go, if you like you can go to the Pitṛloka. If you want to remain here as human being, you can also remain here, but you have to work for it to keep your position, status. Just like if you become rich man, high standard of life, you have to maintain it. Not that it will continue automatically. No, that is not possible, sir. This material world is not like that: you get one position and it will continue. No. A little discrepancy, immediately deteriorate your position. So you have to maintain it.
So if you want to maintain yourself within this Bhurloka . . . there are above this Bhūrloka, Bhuvarloka, Janaloka, Tapoloka, Maharloka. There are so many planetary system. And down also, Tala, Atala, Vitala, Pātāla, Talātala, like that. If you want to go down, you can go down. If you want to go up, you can go. Ūrdhvaṁ gacchanti sattva . . . everything is there; you can do.
