Canto 3 of Bhagavata Purana, chapter 31 describes the movement of the soul in the womb of a human mother. Is it described in any other purana in greater detail?
The embryology or lifecycle of fetus in the womb as described in Bhagavata Purana is also discussed in other puranas.
For example Markandeya Purana - Canto 11 - Conversation between father and son ,(Sumati) jada explains how living beings are conceived and born , and mentions the evils of all existence -
And Agni Purana Chapter Three hundred and sixty nine - Description of absolute dissolution and the process of creation. both are also discussing the topic. Although not as clear and in detail as Bhagavata Purana.
19-20 The soul after having entered the womb dwells in the foetus . It gets hard in the second month. The limbs grow in the third . Bones skin and flesh (are formed) in the fourth (month). Hair grows in the fifth (month) . Heart is formed in sixth. The soul feels pain in seventh.
21 Thus (the child) remains in the womb being covered with the placenta and having hands folded above the head. A eunuch stays in the middle (of the abdomen) , a female (child) on the left side and male (child) on the right side.
22 The child stays in the womb facing the back (of the mother) . There is o doubt that it ( the child) recognises the person in whose womb it stays.
23 It knows fully all the incidents of previous life from birth onwards . A person finds great darkness and (experiences) suffering.
24 In the seventh month it partakes the food eaten by the mother. It becomes extremely restive in the eighth and ninth months.
25 It suffers when there is coition and physical exercise on the part of the mother . It becomes sick when the mother is sick , moment of agony appearing as if lasting for hundreds of years.
26 It is tormented by the past deeds and makes a resolutions : "O Brahman ! After getting out of the womb i will gain the knowledge relating to liberation from this bondage.
27 Being press down by the wind inside mothers womb , it gets out through the Vagina . It gets afflicted in the first month after birth and feels pain when touched with the hand.
The son spoke -
1 " Now human impregnation of women is a seed sown in darkness ; immediately it discharged it sets out from
2 Naraka or swarga . Dominated thereby two seeds attain firmness , O father ! and next the character of a speck - of a
3 globule - of a ball of flesh. As there may be minute seed in the ball of flesh , so it i called a germ. So the five limbs up-
4 grow according to their parts ; and the minor limb also , the fingers , the eyes and nose , the mouth and the ears , grow out of the limbs ; similarely the nails and the other features grow out of
5 them. In the skin is developed the hair of the body , and afterwards the hair of the head .The womb verily increases
6 In size equally with it . Just as the cocoa -nut enlarges together with its shell , so it grows in size. the womb is situated with
7 Its mouth downwards . But at the bottom of the womb the fetus develops , placing its hands on the either side of the knees and its finger in
8 front of them ; behind the knees are the eyes and between the knees is the nose ; and the buttocks rest on the heels ; the arms and legs lie outside.
9 In this way gradually grows human being ,when contained in the womens womb : inn the womb of other
10 creatures , the position of the fetus corresponds to its form.The gastric fluid renders it firm. It lives on the food and drink taken by its mother .Thus the gestation of a living creature is
11 meritorious , and constitutes a means of obtaining merit. Also the cord , which is called as Apyayani , is fixed in its naval and it
12 becomes fixed in the belly of the women . As women's food and drink penetrate into their womb , the fetus increases in size its body is nourished thereby.
13 " Numerous matters of its transmigrations occure to its memory ; hence distressed on this side and on that it becomes
14 dispirited , thinking , ' Never again will I thus act , when once i am delievered from this womb ; assuredly I will so strive
15 that I do not again undergo conception .' Thus it meditates recollecting the hundreds of pain attending existence , which have been experienced aforetime , and which spring from destiny .
16 "Afterwards in the course of time the fetus turns round with its face downwards , since it is born in ninth or tenth month
17 While it is been expelled , it is pained by the wind of the prjapatis ,and it is expelled wailing , being pained by
18 heart by its sufferings .And when from the belly , it falls into an intolerable swoon ; and it gains consciousness
19 when it comes into contact with the air . Thereupon Vishnu's magical power , which effaces consciousness , assails it ; its soul being stupefied thereby , it loses its knowledge.
