THE SCIENCE OF SELF-REALIZATION
that the animal before him is being slaughtered, he will still stand there contentedly eating the grass. This is animal life. He does not know that next time it will be his turn and he will be slaughtered. I have seen it. In a Kālī temple I have seen that a goat was standing there ready to be sacrificed and another goat was very happily eating the grass.
Similarly, Mahārāja Yudhiṣṭhira was asked by Yamarāja, “What is the most wonderful thing in this world? Can you explain?” So Mahārāja Yudhiṣṭhira answered, “Yes. The most wonderful thing is that at every moment one can see that his friends, his fathers, and his relatives have died, but he is thinking, ‘I shall live forever.’” He never thinks that he will die, just as an animal never thinks that at the next moment he may be slaughtered. He is satisfied with the grass, that’s all. He is satisfied with the sense gratification. He does not know that he is also going to die.
My father has died, my mother has died, he has died, she has died. So I will also have to die. Then what is after death? I do not know. This is the problem. People do not take this problem seriously, but the  Bhagavad-gītā  indicates that that is real education. Real education is to inquire why, although we do not want to die, death comes. That is real inquiry. We do not want to become old men. Why does old age come upon us? We have many problems, but this is the sum and substance of all of them.
In order to solve this problem, Lord Caitanya Mahāprabhu prescribes the chanting of Hare Kṛṣṇa. As soon as our heart is cleansed by chanting this Hare Kṛṣṇa mantra, the blazing fire of our problematic material existence is extinguished. How is it extinguished? When we cleanse our heart we will realize that we do not belong to this material world. Because people are identifying with this material world, they are thinking, “I am an Indian, I am an Englishman, I am this, I am that.” But if one chants the Hare Kṛṣṇa mantra, he will realize that he is not this material body. “I do not belong to this material body or this material world. I am a spirit soul, part and parcel of the Supreme. I am eternally related with Him, and I have nothing to do with the material world.” This is called liberation, knowledge. If I don’t have anything to do with this material world, then I am liberated. And that knowledge is called  brahma-bhūta .
A person with this realization has no duty to perform. Because we are now identifying our existence with this material world, we have so many duties. The  Śrīmad-Bhāgavatam  says that as long as there is no self-realization, we have so many duties and debts. We are indebted to the demigods. The demigods are not merely fictitious. They are real. There are demigods controlling the sun, the moon, and the air. Just as there are directors of government departments, so for the heating department
