So Bhagavad-gītā says, yā niśā sarva-bhūtānāṁ tasyāṁ jāgrati saṁyamī (BG 2.69). We are seeing that these people are sleeping, and they are seeing we are wasting our time. This is opposite view. Why? Because their line of action is different, our line of action are different. Now, it is to be decided by an intelligent man whose actions are actually right.
These things are very nicely discussed in Vedic literature. There is another . . . just like this is Īśopaniṣad. Similarly, there is another Upaniṣad, Garga Upaniṣad. So that is the talk between husband and wife, very learned. The husband is teaching the wife. Etad viditvā yaḥ prayāti sa eva brāhmaṇa gargi. Etad aviditvā yaḥ prayāti sa eva kṛpanā (Gargopaniṣad). This real culture of knowledge, one who . . . everyone takes birth and everyone will die. There is no difference of opinion about it. We shall die and they shall die. They can say that, "You are thinking of birth, death, old age and disease. So do you mean to say that because you are cultivating Kṛṣṇa consciousness knowledge, you will be free from these four principles of nature's onslaught?" No. That is not the fact.
The fact is, the Garga Upaniṣad says, etad viditvā yaḥ prayāti. One who quits this body after knowing what he is, sa eva brāhmaṇa, he is brahmin. Brahmin . . . we are offering you the sacred thread. Why? Just you try to understand what is the mystery of life. That is brāhmin. Vijānataḥ. We have read in this verse, vijānataḥ. One who quits this body after knowing things as they are, he is brāhmin.
And etad aviditvā yaḥ prayāti . . . and one who quits this body without knowing the mystery of life, he's a kṛpaṇā. Kṛpaṇā means miser. Just like if you get one million dollars and you could not utilize it, simply you see that, "Oh, I have got this bank balance"—you are happy simply by seeing it—then you are kṛpaṇā. You do not know how to utilize. And one who has got one million dollars and utilizing it and making millions and millions of dollars, he is intelligent.
Similarly, this body is invaluable. One who is utilizing it for culture of spiritual knowledge, he is brāhmiṇ. That is the difference between brāhmin and kṛpaṇā. And one who is utilizing this body like cats and dogs for sense gratification, he is miser. He does not know how to utilize one million dollars. Everyone does not know.
But it is the duty of the father, duty of the state, duty of the teachers to educate from the very beginning. Bhāgavata says that one should not become a father, one should not become a mother, one should not become a teacher, one should not become a king unless they are able to elevate their dependents to this spiritual knowledge, which can save him from repeated birth and death.
