Prabhupāda: So, again Kṛṣṇa, the Supreme Personality of Godhead, is stressing on the point how to avoid death. This is the whole scheme of Vedic knowledge, janma-mṛtyu-jarā-vyādhi-duḥkha-doṣānudarśanam (BG 13.9). But people have no knowledge. They have become just like animal. Animal, you take them to the slaughterhouse, they cannot do anything.
They are becoming slaughtered. So people at the present moment, they are also being slaughtered by the laws of nature. But they do not know, as the animals do not know how to protect. They do not know. The animal thinks that, "What can be done? I must be slaughtered." So the present civilization also given to the laws of nature, being carried away by the waves of nature, and subjected to the repetition of birth, death, old age and disease. No scientist can stop it. But still, they are very much proud of advancement. They do not know the real problem and how to solve it, but still, they are very much proud. Actual problem is this.
So even they do not know, they can hear. Just we are opening centers all over the world—why? Just to give them the chance to hear. To hear. If people only come to these centers, these centers of spiritual knowledge, Kṛṣṇa consciousness movement, hear the Bhagavad-gītā as it is, without any so-called scholastic interpretation, all rascal, as it is, then they also can derive the benefit, so much so that they can also stop their repetition of birth, death and old age. It is so nice thing.
Anye. Anye means general public, not very important men. Anye. Anye tu evam ajānantaḥ. They do not know—because they are like animals—what is kṣetra . . . Kṛṣṇa is discussing in this chapter what is kṣetra, what is kṣetra-jña, what is knowledge, what is knowable, what is prakṛti, what is puruṣa. Who is studying all these things? There is no institution, no school, college, university, to study these. They have medical college. Kṣetra means this body. Idaṁ śarīraṁ kṣetram ity abhidhīyate (BG 13.2). So they has little knowledge about this anatomical, physiological, condition of this body, but they do not know the kṣetra-jña. Kṣetra-jña they do not know.
They may know something. But Kṛṣṇa says, kṣetra-kṣetrajñayor jñānaṁ yaj jñānaṁ tad mataṁ mama (BG 13.3). Unless you know the kṣetra and kṣetra-jña both, then your knowledge is imperfect. The medical man, very experienced medical man, attending a man on the deathbed, oxygen gas, injection, everything is supplied, but the man dies. And when he dies, the medical man says: "We cannot say what has happened. We have tried our best with the modern medical appliances, but we do not know what has happened." Therefore their knowledge is imperfect. They cannot say. They do not know that there is the soul, kṣetra-jña, who has now left this body; therefore it is nothing but a lump of matter.
Then puruṣa-prakṛti. Prakṛti is this material nature; puruṣa, the living entity. The inferior puruṣa and the superior puruṣa. Anumantā upadraṣṭā, the Supersoul, He is overlooking the activities of the jīva soul, and according to his karma, He is giving a different type of body, kṣetra. Again he is working. Again he is creating another situation. This vast knowledge is unknown to the modern educational department. But here it is in the Bhagavad-gītā. They can take advantage of it. But the fools and rascals will not take advantage. They will remain like animals in the ignorance, like cats and dogs. That is their business.
