So that is our mistake. Our mistake is that we have got advanced or developed consciousness. We should utilize it for going back to home, back to Godhead. Why should we misuse it unnecessarily? And you are not perfect. Suppose you are studying the machine throughout the whole life. What you will get that? Can you make the machine to your favor, that this machine will not be lost, there will be no death? You all scientists, you are studying the machine. Have you found out any means that there will be no death? Where is that knowledge? Death will be there. You study the machine or do not study the machine, in due course time, the death will come and will take you. The machine will stay.
So this is intelligence. Janma-mṛtyu-jarā-vyādhi-duḥkha-doṣānu. . . (BG 13.9). You cannot cure even one disease. You are embarrassed with the cancer disease. You find out how the cells are working, how it can be changed, and there will be no cancer. No, that you cannot do it. You go on studying simply, waste your time. So śāstra says, "Don't waste your valuable time in that way. Try to understand God. Use your intelligence for this purpose." Tapaḥ. Tapo divyaṁ yena śuddhyet sattvam (SB 5.5.1). You have to undergo austerities that you may not be subjected to this machine. That is your business—not to study the machine. How to become independent of the machine. So long you are in this material world, you are desiring differently. Nature is supplying you a different type of machine, and you are busy. Then again, the machine is broken, then you accept another machine. This is going on.
So your problem is to stop this repetition of birth, death, old age and disease. Come to your spiritual life. That is your business. That is the instruction of the śāstras. The machine maintaining, everyone knows it. The dog knows how to maintain the machine. He eats according to the necessity of his doggish body. So we also know, human body. So that is natural. That is. . . The supplies are already there. You cannot manufacture supplies. That is the Vedic instruction: eko yo bahūnāṁ vidadhāti kāmān, nityo nityānāṁ cetanaś cetanānām (Kaṭha Upaniṣad 2.2.13). There are many millions and trillions of living entities, and there is another living entity: that is God. So this another, one, singular number, there is no second, duplicate, of this one. But we ordinary living entities, we have got many millions of duplicates. Therefore two things are used: nitya, nityānām. Nityānām means plural number. Many, many, innumerable. You cannot count. Asaṅkhyā, the jīva is. Asaṅkhyā means nobody can count. And above this asaṅkhyā, innumerable living entities, there is one prime living entity. God is also a living entity. He is also like us. In your Bible there is there: "Man is made after God." Is it not? So God is living entity, and we have got this form after the form. . . God is two-handed; we have got two hands. So that is a fact. This human form of life is made according to the form of Lord. It is imitation; that is real. Sac-cid-ānanda-vigrahaḥ, īśvaraḥ paramaḥ kṛṣṇaḥ (Bs. 5.1).
