Prabhupāda: So what you will learn about that, by studying the human species? You study Kṛṣṇa. This is sufficient. There are 400,000 species of life. What will you benefit by studying? The botanist, the geologist, the biologist, they are doing that. Let them do that. You have to do, how to understand Kṛṣṇa. But you can simply know that there are so many different... That much, that is sufficient. What is the use of? Now, suppose I am using this microphone. What is the use of studying how it is manufactured? Why...? That's all right. It is already manufactured. Let me use it. That's all. Why should I waste my time, "How it is manufactured?" I am not going to be manufacturer of microphone. I am going to become servant of Kṛṣṇa. That's all.
Devotee: Does the word nirvāṇa mean Kṛṣṇa?
Prabhupāda: Nirvāṇa means, as I told you, you forget all nonsense, what you have learned. That is nirvāṇa. Because you have learned so many nonsense things, if you finish that "We don't want this," that "Whatever is done is done. Now let me try to understand Kṛṣṇa," that is nirvāṇa. Nirvāṇa means finished. Nirvāṇa means finished. Do you understand? Finish this all nonsense, material business. Now begin spiritual life. That is nirvāṇa.
Brahmānanda: You say that Kṛṣṇa consciousness solves the problem of death. Does it mean that we won't die?
Prabhupāda: Yes. As soon... That is said. Die means this is the last time. Because you have got this body, you will die. But after this death, no more death.
Brahmānanda: So we will die, but it will be the last death.
Prabhupāda: That is not die. We never die, but we change the body. But the change of body, we take as death. Otherwise there is no death. Na jāyate na mriyate vā. There is no death, no birth, of the soul. But just like the dress, the coat, may be old and you throw away, that means you are not annihilated. Your coat is annihilated, shirt is... Similarly, na hanyate hanyamāne śarīre (BG 2.20). After being destruction of this body, you are not destroyed. You live, but in the material existence you accept another material body. That means you continue the process of birth and death. But if you understand Kṛṣṇa, if you become fit to enter into the society of Kṛṣṇa, then you get only that spiritual body, no more material body. Tyaktvā dehaṁ punar janma naiti mām eti (BG 4.9), "He comes to Me." That is your eternal life.
Puṣṭa-kṛṣṇa: Śrīla Prabhupāda, in the Seventh Chapter Kṛṣṇa explains that He is the taste of water, and in different chapters that He's the source of light in all luminous objects. So when we think like this, how should we think of Kṛṣṇa? In His personal form?
Prabhupāda: That is already stated. There is no difficulty. Why do you ask this question? It is said, raso 'ham apsu kaunteya (BG 7.8), that "I am the taste of the water." So where is the difficulty? You take the taste of the water. There is taste, and Kṛṣṇa says, "I am that taste." So you understand that, that "This taste is Kṛṣṇa." Where is the difficulty? You do not know what is Kṛṣṇa, but Kṛṣṇa says "I am this taste." Why don't you accept it? Then you know Kṛṣṇa. According to your position, you understand Kṛṣṇa. Kṛṣṇa says, "I am this." So take it, that taste of water... As soon as you drink water, "Oh, here is Kṛṣṇa." So you will... Smaraṇam. Śravaṇaṁ kīrtanaṁ viṣṇoḥ smaraṇam (SB 7.5.23). Then you will at least memorize Kṛṣṇa. That will enlighten your spiritual life. Because you will say... You take... Just like I am taking water several times, and if each time I remember, "Here is the taste, Kṛṣṇa," then Hare Kṛṣṇa. Chanting of Hare Kṛṣṇa, whatever you will be going.
