The Supreme Lord says:
Under the direction of the Supreme Lord and according to the fruit of His works, the living entity, the soul, is introduced into the womb of a woman through a drop of male seed to assume a particular body form.
On the first night, there is fusion of the sperm and the ovum, and on the fifth night, this germ becomes like a bubble. On the tenth night, this one develops and takes the form of a plum, after which it gradually transforms into a mass of flesh or an egg, as the case may be.
In one month the head appears, and after two months the hands, feet and other parts of the body take shape. At the end of the third month the fingers, toes, nails, hair, bones and skin appear, as well as the genitals and other orifices of the body, that is, the eyes, nostrils, ears, mouth and anus.
Four months after conception, the seven essential components of the body, namely chyle, blood, flesh, fat, bones, marrow and seminal fluid are created. At the end of the fifth month, hunger and thirst set in, and at the end of the sixth, the fetus, imprisoned in the amniotic cavity, begins to move on the right side of the abdomen.
When the body is fully formed at the end of the sixth month, the child, if it is a boy, begins to move on the right side; if it is a girl, she will move on the left side.
Ensuring its nutrition from the food and drink ingested by the mother, the fetus grows and remains confined in this abominable receptacle of excrement and urine, where all kinds of worms proliferate.
Constantly bitten all over the body by the hungry worms also in the mother's womb, the delicate child suffers terribly and sinks into unconsciousness at every moment, subjected to this terrible condition.
Because the mother takes bitter, pungent, too salty or too sour food, the child's body is endlessly subject to almost intolerable pain.
Enclosed in the amniotic cavity and surrounded on the outside by the intestines, the child remains lying on one side of the abdomen, its head inclined towards its belly and its back and neck curved like a bow.
