If by evolutionary process through the channel of so many species of life, 900,000 aquatics. Jalajā nava-lakṣāni sthāvarā lakṣa . . . two millions trees and plants, then 1100,000 insects, and ten . . . one million species of birds, and then 33,000,000 species of animals, four-legged animals, paśu. And then we get this human form of life, especially civilized form of life. Then what is next? That question nobody inquires, neither there is answer by the so-called modern scientist, that what is next.
But the answer is there. Answer is there in the Vedic literature that there is higher planetary system. 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.
