All kinds of knowledge, you can achieve from the Vedic language. There is Dhanur-veda, Āyur-veda, Jyotir-veda and all kinds. Veda means knowledge. So for military art, if you want to consult Vedic literature, you will get complete information, perfect. Similarly, Jyotir-veda. Jyoti means the luminaries in the sky, the stars. You can get. We are trying to go to the moon planet and wasting our time and energy, but if you consult Vedas, you get full information of the moon planet, sun planet or any other planet. There are millions and millions of trillions of planets. You can get all, Brahmaloka, up to the topmost planet. Jyotir-veda. That is called Jyotir-veda. And the Dhanur-veda. Āyur-veda. Āyuḥ means duration of life. And nobody wants to be diseased. So that means medical science. That is also fully there.
So this is the prescription given by Śrīmad-Bhāgavatam, "If you want to become without any fear..." Because the material life means we are all full of fearfulness. And therefore Kṛṣṇa, the supreme father of everyone, of all living entities, in all forms, sarvātmā, He says in the Bhagavad-gītā that "I am the seed-giving father of all these living entities." Just like father impregnates the mother by giving the seed, similarly, this material world, material nature, is our... This body is also material. Similarly, this huge material cosmic manifestation is supposed to be the mother, and the father is God, or Kṛṣṇa, who impregnates this seed of the living entities, and therefore, when there is creation, they come out as children of this material world. Just like a woman is pregnant and the child comes out, similarly, this material world is impregnated by the seed-giving father. So that is a different article from this matter. Otherwise, why a woman does not become pregnant automatically? Why? Can anyone answer? Why the seed-giving father is necessary? Let women produce children automatically. No, that is not possible. Therefore, for producing all these living entities in different forms of life, the seed-giving father is required, and that is God, Kṛṣṇa. Is there any bad logic? There is confirmation in the śāstra. Kṛṣṇa says, ahaṁ bīja-pradaḥ pitā: (BG 14.4) "I am the seed-giving father." And is it possible to produce life without the father? Is it possible? Then why these rascal scientists say that "Now we shall produce life"? How you can do it? It is not possible. This is rascaldom. Because we are living entities, therefore even in the Christian world the Supreme Lord God is accepted as the supreme father. "O father, give us our daily bread." It is very good, accepting the Supreme Lord, the supreme father. Everyone must accept. That is human life. That is human knowledge. That is common sense knowledge, that "If I am produced by my father, so, so many living entities, wherefrom they have come? They have come from the supreme father." Sarvātmā. He is called sarvātmā. Śrotavyaḥ kīrtitavyaś ca.
So if you want freedom from this fearfulness or this material existence... Material existence means struggle for existence. This is material. Everyone has struggle: "I want to stay. I want to..." In your country there has been so much fight, the French Revolution and so many fighting, fighting between the Protestant and the Catholic. And your Napoleon Bonaparte, he also fought. So fighting, this is called struggle for existence. Everyone wants to exist, and he has to fight. At least, we have to fight with the winter season. If there is no fighting, so at least there must be fighting with the winter season or summer season. Without fighting, you cannot stay. Without fighting, you cannot stay. That is called struggle for existence and survival of the fittest. You must be fit. This is called material world. And spiritual world means there is no fight; simply friendship, that's all. This is spiritual world. Vaikuṇṭha. Vaikuṇṭha. Kuṇṭha means "anxiety," and vaikuṇṭha means "without anxiety."
So we have been put into this place of anxiety on account of our rebellious condition against God. That is the cause of all material existence. Kṛṣṇa-bahirmukha hañā bhoga vāñchā kare. We should know this, that "Why we are put into this condition of struggle for existence, always fearfulness anxiety? Why we are put into this condition? We don't want it." This is human life. When this inquiry will come to a human being, then he is human being. Why? So long this "Why?" question does not come, he is animal. The animal does not question that "Why I am put into the slaughterhouse? Why I have brought, I have been brought here to be slaughtered?" Animal. Similarly, if a human being does not understand that "I have been put into this material world for being slaughtered by the laws of material nature. Never mind I am Napoleon or an ordinary man, I will be slaughtered..." Therefore it is called martya-loka, "the universe of being slaughtered." Nobody wants. Just like the animal does not want to be slaughtered, but he is, by force, it is slaughtered. Similarly, nobody wants death, but we are forced. Even such a big man like Napoleon, he wanted to complete that arch, but he was slaughtered before his desire was fulfilled. This is material nature. You must be slaughtered before his desire was fulfilled. This is material nature. You must be slaughtered as soon as required.
