We can see at night, there are so many millions and millions of planets. So we can go there. That is stated in the Bhagavad-gītā, that ūrdhvaṁ gacchanti sattva-sthāḥ (BG 14.18). Now we have come to the human form of life. If we cultivate sattva-guṇa . . . the material word is composed of three modes of material nature: the sattva-guṇa, rajo-guṇa and tamo-guṇa. So if we remain in the sattva-guṇa, then we shall be promoted to the higher planetary system. If we remain in rajo-guṇa, then we shall remain where we are. And if we remain in tamo-guṇa, ignorance, that, then we shall go down again to the lower species of life. This is the laws of nature.

The rascals, they are thinking they are independent. That is . . . they are not independent. Completely under the control of the material nature. Otherwise why there are different species of life? Where is the arrangement? Arrangement is there. If you remain in sattva-guṇa, then you get higher form of life. Nature's law is so perfect that it hasn't got to create; it is automatically. Just like if you infect some disease, germs, you will automatically suffer from that disease. Similarly, if we are in contamination, sattva-guṇa, rajo-guṇa . . . sattva-guṇa here . . . sattva-guṇa is also a contamination. And what to speak of rajo-guṇa, tamo-guṇa? So this is called pravṛtti-mārga.
