The human life is not meant for that purpose. This is the defect of modern civilization. Nāyaṁ deho deha-bhājāṁ nṛloke kaṣṭān kāmān arhate viḍ-bhujāṁ ye (SB 5.5.1). Viḍ-bhujām, the hog, who eats stool, he's also struggling for the same thing. What is that? Eating, sleeping, mating and defending, that's all. So is that human life is also simply meant for this purpose? No. Human life is meant for tāpo divyaṁ yena śuddhyed sattvam (SB 5.5.1). You have to purify your existence. My existence is now impure. In the Bhagavad-gītā we learn, na jāyate na mriyate (BG 2.20). The living entity, the soul, never takes birth, never dies, but I am subject to birth and death. So this problem does not come. They are simply making adjustment a temporary problem. That is not human civilization. Vedic civilization means to solve the major problems of life. That is Vedic civilization. Janma-mṛtyu-jarā-vyādhi-duḥkha-doṣānudarśanam (BG 13.9). They don't care for these troubles.
Formerly, people were very happy so far material conditions were concerned. They had no complaint. Everyone was happy, everyone was getting ample food. And why they shall not get? The birds, beasts, they are getting their ample food, even up to death. There is no complaint amongst the birds and beast, unless one is in the human society. Otherwise in the jungle there are major portion of the animals and birds.
They have no complaint. They do not come in the city that, "We have this complaint." They are happy. They are getting ample food; life is very happy. They have got their eating, they have got their sleeping, they have got their mates for sex life and they know how to defend. Everything is there. There is no problem. Only in the human society they have created problems, because they have no knowledge. The so-called knowledge is useless. Unless you cannot (sic) solve the problems, what is the meaning of this knowledge? Therefore Kṛṣṇa says knowledge means one must know this is my real, acute miserable condition of life, janma-mṛtyu-jarā-vyādhi-duḥkha-doṣānudarśanam (BG 13.9). This is knowledge.
