I do not wish to take birth; still, I am forced to go into the womb of my mother by the laws of nature. After giving up one body I enter another body. And there is no security what kind of body I shall get next. It may be human body, it may be animal, it may be trees or it may be better than human being, because there are three divisions. One division is called demigod, and one division is called the human being. The other division is called lower than the human being. Nṛ-tiryag-deva. Deva means who are very highly advanced in knowledge. They are called devas, and God conscious, Kṛṣṇa conscious, such men. There are different planets also for different kinds of living entities.
So this knowledge is being imparted by the Supreme Personality of Godhead, not by a person like me or like you who are defective in four principles. That I was going to explain. The four defects are that we commit mistakes, we are illusioned, and our senses are imperfect and therefore sometimes we cheat others. Although I know . . . I do not know a subject matter very clearly; still, I say something as authority. That is cheating. We should not cheat. If we want to give knowledge to the people, we must give perfect knowledge.
So perfect knowledge, how it can come? The perfect knowledge can come from the Supreme Personality of Godhead. This is the process of acquiring knowledge, so far we are concerned. Evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2).
