If somebody comes to encroach upon your property, you kill him immediately. That is said. But not kill unnecessarily. Just like Arjuna was taught, "Kill them. They have insulted your wife, they have encroached upon your property. They must be killed." That is allowed. But you don't be aggressive. So ahāra-nidrā-bhaya, and sex, sex life. Yes. Just get yourself married and have sex life only for children, not for other purpose.
So kāmasya nendriya-prītiḥ. Kāma means we have got some demands of the body. That is called kāma, or lust. So that does not mean that we have to gratify the senses. As far as necessary, we shall utilize it. Nendriya-prītiḥ. Then how to live? Now, kāmasya, that satisfaction of the senses should be allowed just to keep myself fit. I must live. Even if I become Kṛṣṇa consciousness, I must work. So that is allowed.
But what is my . . . what is your main business? Jīvasya tattva-jijñāsā nārtho yaś ceha kārmabhiḥ. Your only business is to understand what you are, what God is, what is this world, what is your relationship. This is your main business. This is your main business. Not that you earn money and employ it for sense gratification, as it is going on in this materialistic way of life. Nobody is inquisitive to know what he is. How can he? Very big businessman or very rich man or so-called advancement, can you say what you are? What is your duty? Nobody can say.
So that is the main business, that jīvasya tattva-jijñāsā nārtho yaś ceha kārmabhiḥ. By your . . . by the result of your activity . . . or your main activity should be inquiring about your spiritual existence. So this should be our inquiry.
