Every living being has got a particular type of body. Dehino 'smin yathā dehe. And what is the nature of that body? Now, here the matter is being explained that how we change our body, how . . . but, but, but, because that is a difficult problem for us, because we are engrossed with the idea of identifying this body with the soul. Now, the first A-B-C-D of spiritual knowledge is to understand that, "I am not this body." Unless one is firmly convinced that, "I am not this body," he cannot make progress in the spiritual line. So the first lesson in the Bhagavad-gītā is taken in that way. So here it is, that dehino 'smin. Now, dehī, the soul, soul. Dehī means soul. One who has accepted this body, material body, he's called dehī. So asmin, he is there. He is there, but his body is changing. The body is changing.
Now, our body was formed in the womb of my mother. That is also described in the Śrīmad-Bhāgavata, the physiology, physiology of this body. It is said there that according to our karma we are put through the semina of the father, injected into the womb of the mother. And the father's secretion and the mother's secretion, that is emulsified and takes the form of a pea, and that pea gradually develops. In three months, there are holes, nine holes: the eyes, ears, nose and the . . . just like we have got nine holes. And in seven months the whole body is complete. Then the child gets consciousness. And ten months it is just ready to come out.
So by air, the same air, forces the child to come out of the mother's connection. Because so long a child remains within the womb of the mother, she, she takes through the mother, so there is intestinal connection between the child and the mother. So after the child comes out, the intestinal connection is cut away and he becomes a separate identity. That is the law.
