Just try to understand that I am thinking, "I am such big man," "I am minister," "I am president," "I am this," "I am Nārāyaṇa," up to the last stage, "I am Nārāyaṇa." But if we soberly think that "If I am Nārāyaṇa, then I must be the controller. I must be controller of everything. But why I am controlled by the toothache? As soon as there is some pain in the tooth, I voluntarily go to a dentist to be controlled by him. Then how I become Nārāyaṇa?" In this way, if one studies his life, whole, that, he'll find it that he's fully controlled by something more. Fully controlled. And that control is of the material nature. Who can say that he is not controlled by the material nature? That is not possible. Daivī hy eṣā guṇamayī mama māyā duratyayā (BG 7.14). Material nature will oblige you. You are very nice, good-looking young man. Material nature will not allow you to remain as very good-looking young man. You must become old man. Your teeth must fall down, your hairs must grow gray, and you'll look ugly. Why? But he does not think. This is called ignorance, ajñāna.
Therefore Kṛṣṇa says, jñānaṁ te 'haṁ sa-vijñānam (BG 7.2): "I'll speak to you about jñāna." Everyone is in ajñāna and falsely thinking that he is some very important person. This is ajñāna. Real jñāna, as will be explained here, is to receive from Kṛṣṇa. So Kṛṣṇa is giving knowledge in the Bhagavad-gītā. He'll speak in later chapters that "The real jñāna is to surrender unto Me." This is real jñāna. Kṛṣṇa will say in the Eighth Chapter, bahūnāṁ janmanām ante jñānavān māṁ prapadyate (BG 7.19): "After many, many births." So we are . . . Today I may be minister, and tomorrow, after death, I may become a dog. But that is not in my control. You cannot say that "I am minister. I am this. I am that. I am high-court judge or very important man. So I am ordering material nature. Although I shall die, next life I shall become again high-court judge or Nārāyaṇa, something." No. That is not possible. You are fully under control. You have given a license to enjoy or suffer in this body, and in this body, as soon as it is finished, karmaṇā daiva-netreṇa jantur . . . (SB 3.31.1), and then you'll get another body.
So this jñāna, even this jñāna, that change of body is not there. Throughout the whole world, big, big professor, big, big educationist, they do not believe in the next birth—99.9%, they do not. But this is a fact. There is. Tathā dehāntara-prāptiḥ. Kṛṣṇa says. And we understand this also. Kṛṣṇa gives this example: dehino 'smin yathā dehe kaumāraṁ yauvanaṁ jarā (BG 2.13). This child is becoming kumāra; a kumāra is becoming boy; boy is becoming young man; young man is becoming old man. So these changes are going on; still, he does not know that "After this old body is finished, I shall have to accept another body." So this is ignorance. Therefore we have to take knowledge from the most perfect Personality of Godhead, Kṛṣṇa. This is real knowledge.
