We Are Not These Bodies, We Are Soul
…within this body there is soul, and the body is changing every moment, but the soul is there. Just as a soul comes from the womb of his mother with a small body, and that small body changes—it becomes the body of a boy, it becomes the body of a youth, then it becomes the body of an old man, then it vanquishes… That we have to admit. We may say that the body is growing, but actually, the fact is, body is changing. It is medically admitted that we are changing our body every second. We are changing our blood corpuscles, and therefore a change of the body is taking place, and that is being manifested in a different shape only. Actually, we are changing every moment our body. So the ultimate change, when this body cannot be worked any more, just like a dress, when it is torn, when it is too old, you have to change it. Similarly, when this body becomes useless, no more, it cannot be pulled on any more, you take another body. Tathā dehāntara-prāptir. As we are, in our practical life, we are changing our body every moment, similarly, the last stage of changing this body is called death. Just as I give up this body, I have to enter into the womb of some kind of mother. These things are explained in the Vedic literatures. (Srila Prabhupada from lecture; San Francisco, April 2, 1968)
The soul is eternal, it is changing body, different bodies, and there are 8,400,000 different forms of body. According to his desire, he is entering another body.
…in the hundreds and thousands of universities all over the world there is no department of knowledge where the science of the soul is taught. Actually, we are all spirit soul. From Bhagavad-gītā we understand that we are transmigrating from one body to another, even in our present lives. All of us had at one time the body of a small baby. Where is that body? That body is gone. Presently I am an old man, but I remember that I was once a small baby. I still remember when I was about six months old; I was lying down on the lap of my elder sister, who was knitting, and I was playing. I can remember that, so it is possible for everyone to remember that he had a small body. After the baby’s body I had a boy’s body; then I had a youthful body, and now I am in this body. Where are those bodies? They are gone now. This is a different body. It is explained in Bhagavad-gītā that when I give up this body, I will have to accept another body. It is very simple to understand. I have changed so many bodies, not only from childhood to boyhood to youth, but according to medical science we are changing bodies every second, imperceptibly. This Process indicates that the soul is permanent. Although I have changed many bodies, I remember my baby body and my childhood body—I am the same person, soul. Similarly, when ultimately I change this body, I shall have to accept another. This simple formula is stated in Bhagavad-gītā. Everyone can reflect on it…(Srila Prabhupada from; Krsna Consciousness The Topmost Yoga System)
A person or an animal is not the material body; rather, the material body is the covering of the living being. Bhagavad-gītā compares the body to a dress and elaborately explains how one changes dresses one after another. The same Vedic knowledge is confirmed here. The living being, the soul, is constantly changing bodies one after another. Even in the present life, the body changes from childhood to boyhood, from boyhood to youth, and from youth to old age; similarly, when the body is too old to continue, the living being gives up this body and, by the laws of nature, automatically gets another body according to his fruitive activities, desires and ambitions. The laws of nature control this sequence, and therefore as long as the living entity is under the control of the external, material energy, the process of bodily change takes place automatically, according to one’s fruitive activities.
