Srila Prabhupada: What is the current scientific knowledge about the spirit soul?
Dr. Benford: We have virtually no scientific knowledge about the soul.
Srila Prabhupada: Therefore you have actually made no advancement in scientific knowledge.
Dr. Benford: Well, scientific knowledge is a different class of knowledge.
Srila Prabhupada: Perhaps. There are so many departments of knowledge: the medical study of the body, the psychological study of the mind, and ultimately spiritual, transcendental knowledge. The body and mind are simply the coverings of the spirit soul, just as this shirt and coat are coverings for your body. If you simply take care of the shirt and coat and neglect the person who is covered by this shirt and coat, do you think that this is advancement of knowledge?
Dr. Benford: I think that there is no category of knowledge that is useless.
Srila Prabhupada: We don't say that this scientific knowledge is useless. Mechanics, electronics--this is also knowledge. But different departments of knowledge differ in their comparative importance. For example, if someone wants to cook nicely, this is also a science. There are many different departments of knowledge, but the central point is atma-jnana--self-knowledge, the knowledge of the soul.
Dr. Benford: The only form of knowledge that is verifiable--that is, verifiable in the sense of getting everybody to agree with it--is that which can be proved logically or experimentally.
Srila Prabhupada: The science of the self can be verified logically.
Dr. Benford: How so?
Srila Prabhupada: Just consider your body. You once had the body of a child, but now you don't have that body anymore; you have a different body. Yet anyone can understand that you once had the body of a child. So your body has changed, but you are still remaining.
Dr. Benford: I am not so sure it is the same "I."
Srila Prabhupada: Yes, you are the same "I." Just as the parents of a child will say, after he has grown up, "Oh, just see how our son has grown!" He is the same person; his parents say so, his friends say so, his family says so--everyone says so. This is the evidence. You have to accept this point, because there is so much evidence. Your mother will deny that you are a different person, even though you have a different body.
Dr. Benford: But I may not be the same being that I was.
Srila Prabhupada: Correct. "Not the same" means, for example, that a young child may talk nonsense now, but when he gets an adult body he does not speak foolishly. Although he is the same person, along with his change in body he has developed different consciousness. But the spirit soul, the person, is the same. He acts according to his body, that's all--according to his circumstances. A dog, for example, is also a spirit soul, but because he has a dog's body he lives and acts like a dog. Similarly, when the spirit soul has a child's body, he acts like a child. When he has a different body, the same soul acts like a man. According to circumstances his activities are changing, but he is the same. For example, now you are a scientist. In your childhood you were not a scientist, so your dealings at that time were not those of a scientist. One's dealings may change according to circumstances, but the person is the same.
Therefore, the conclusion is tatha dehantara-praptir dhiras tatra na muhyati: "When this body is finished, the soul gives it up and accepts another body." (Bhagavad-gita 2.13) Tatha dehantara. Dehantara means "another body." This is our Sanskrit knowledge from the Bhagavad-gita. When the spirit soul is injected into the womb of a woman, it forms a little body. Gradually, through the emulsification of secretions, the body develops to the size of a pea because of the presence of the spirit soul. Gradually the body develops nine holes--eyes, ears, mouth, nostrils, genitals, and rectum. In this way the body is developed to completion in seven months. Then consciousness comes.
Dr. Benford: At seven months?
Srila Prabhupada: Yes. The child wants to come out. He feels uncomfortable; therefore he prays to God to kindly release him from the bondage. He promises that when he gets out he will become a devotee of God. So after nine months he comes out of the womb. But unless his parents are devotees, due to circumstances he forgets God. Only if the father and mother are devotees does he continue his God consciousness. Therefore, it is a great fortune to take birth in a family of Vaisnavas, those who are God conscious. This God consciousness is real scientific knowledge.
Dr. Benford: Is it true that the children of all such parents are somewhat spiritually superior to the children of other parents?
Srila Prabhupada: Generally, yes. They get the opportunity of being trained by the mother and father. Fortunately, my father was a great devotee, so I received this training from the very beginning. Somehow or other I had this spark of Krsna consciousness, and my father detected it. Then I accepted my spiritual master. In this way I have come to this stage of sannyasa [the renounced monastic order]. I am very much indebted to my father, for he took care of me in such a way that I became perfectly Krsna conscious. My father used to receive many saintly persons at our home, and to every one of them he used to say, "Kindly bless my son so that he may become a servant of Radharani [Lord Krsna's eternal consort]." That was his only ambition. He taught me how to play the mrdanga drum, although sometimes my mother was not very satisfied. She would say, "Why are you teaching him to play mrdanga?" But my father would say, "No, no, he must learn a little mrdanga." My father was very affectionate to me. Therefore, if due to past pious activities one gets a good father and mother, that is a great chance for advancing in Krsna consciousness.
Dr. Benford: What will happen to you and your students next?
Srila Prabhupada: We are going back to Krsna. We have got everything: Krsna's name, Krsna's address, Krsna's form, Krsna's activities. We know everything, and we are going there. Krsna promises this in the Bhagavad-gita (4.9):
janma karma ca me divyam
evam yo vetti tattvatah
tyaktva deham punar janma
naiti mam eti so 'rjuna
"One who knows Me in truth, scientifically," Krsna says, "is eligible to enter into the kingdom of God. Upon leaving the body, he does not take his birth again in this material world, but attains My eternal abode."
Dr. Benford: How do you know that people return in some other form?
Srila Prabhupada: We see that there are so many forms. Where do these different forms come from--the form of the dog, the form of the cat, the form of the tree, the form of the reptile, the forms of the insects, the forms of the fish? What is your explanation for all these different forms? That you do not know.
Dr. Benford: Evolution.
Srila Prabhupada: Not exactly. The different species are already existing. "Fish," "tiger," "man"--all of these are already existing. It is just like the different types of apartments here in Los Angeles. You may occupy one of them according to your ability to pay rent, but all types of apartments are nevertheless existing at the same time. Similarly, the living entity, according to his karma, is given facility to occupy one of these bodily forms. But there is evolution, also--spiritual evolution. From the fish, the soul evolves to plant life. From plant forms the living entity enters an insect body. From the insect body the next stage is bird, then beast, and finally the spirit soul may evolve to the human form of life. And from the human form, if one becomes qualified, he may evolve further. Otherwise, he must again enter the evolutionary cycle. Therefore, this human form of life is an important juncture in the evolutionary development of the living entity.
In the Bhagavad-gita (9.25) Krsna says,
yanti deva-vrata devan
pitrn yanti pitr-vratah
bhutani yanti bhutejya
yanti mad-yajino 'pi mam
In other words, whatever you like you can achieve. There are different lokas, or planetary systems, and you can go to the higher planetary systems where the demigods live and take a body there, or you can go where the Pitas, or ancestors, live. You can take a body here in Bhuloka, the earthly planetary system, or you can go to the planet of God, Krsnaloka. This method of transferring oneself at the time of death to whatever planet one chooses is called yoga. There is a physical process of yoga, a philosophical process of yoga, and a devotional process of yoga. The devotees can go directly to the planet where Krsna is.
