You can utilize this body properly for higher standard of life. You can go to the higher planetary system. The higher planetary system begins from the sun. That is another subject matter. But so far we get information from Śrīmad-Bhāgavatam, there sun, then moon, according to Bhāgavatam. And I think . . . we were talking about these things, that whether the moon is the first planet or the sun is the first planet. So far we understand from Vedic literature, the moon is the second planet. The sun is the first planet. If we consider like that, then moon is beyond the sun planet. The estimation is there in the Śrīmad-Bhāgavatam: 1,600,000 miles above the sun the moon is situated. Now, if we take consideration of the sun planet situated 93,000,000 miles from earth, then add 1,600,000 miles again, it comes to 15,000,000's . . . 95,000,000's miles away from the earthly planet. And how you can reach there in four days, 95,000,000 miles away? If we apply our common sense, then it appears they have never gone to the moon planet. It is all bogus propaganda. It is not possible.
So śāstra-cakṣuṣāt: our knowledge should be through the śāstra. That is practical. And our process of knowledge is this: we get knowledge from śāstra, like Bhagavad-gītā, Śrīmad-Bhāgavatam, Vedic knowledge. We do not claim to be very big scientists. That is not possible. But we get knowledge from the best scientific man, or person, the Personality of Godhead, Kṛṣṇa, Vyāsadeva, Nārada, Asita, Devala, later on the ācāryas, Rāmānujācārya, Madhvācārya, Śaṅkarācārya, Caitanya. Our process of knowledge is not any speculation: "It may be," "Perhaps." No. We don't accept this knowledge. "It may be," "Perhaps"—these are all foolishness. That means one who has no perfect knowledge, he will say: "It may be," "Perhaps." One who has definite knowledge, why he will say, "It may be"? It must be. That is knowledge. Just like we get knowledge from the śāstra, jalajā nava-lakṣāni: "There are nine hundred (thousand) species or forms of life in the water." So we have not gone into the water, but we get from the authorities, Padma Purāṇa, and we accept it.
