Advanced Embryology in the Śrīmad-Bhāgavatam

The Hare Kṛṣṇa movement transplanted from the timeless vedic tradition into the western world by His Divine Grace A.C. Bhaktivedanta Swami Prabhupāda is based on authorized revealed scriptures, of which Śrīmad-Bhāgavatam is the formost. Śrīmad-Bhāgavatam written down by Śrīla Dvaipāyana Vyāsa is the natural commentary on the Vedānta-sūtra, which in turn is the summary of the four VedasṚg, Yajur, Sāma and Atharva. Śrīla Prabhupāda summarizes the importance and purpose of vedic literature in one of his purports:

“The Vedas are compared with the desired tree because they contain all things knowable by the human being both for mundane necessities as well as spiritual realisation. The Vedas contains regulated principles of knowledge covering social, political, religious, economical, military, medical, chemical, physical, metaphysical and all that may be necessary for the proper up keep of the body and the soul together and above all there is specific direction for spiritual realisation also. Regulated knowledge means to raise the living entity gradually to the spiritual plane and the highest spiritual realisation is to know the Personality of Godhead as the reservoir of all mellows (Rasas).” (SB 1.1.3 purport)

Fools often object: “These are some fairy-tales of primitive people who were freaking out because there were lightning and thunders in the sky…” Unfortunately for them, it will not be so easy to prove this assumption. In the light of modern science, the statements and mind-blowing details of different aspects of material nature (to start with) described in the Śrīmad-Bhāgavatam call for attention of serious Absolute Truth seekers who are willing and ready to go beyond the limited range of sense perception, mental speculation, intellectual acrobacy and egotistical “I know everything” self-deception.

One astonishing description, amongst many, is the profound and extremely accurate account of the development of a human, from the stage of gametes (ovum and sperm), through the stages of an embryo and fetus within mother´s womb up to the point of delivery and after.

It is a fact, that from a certain point of time when the developing body acquires an observable mass, its description is not a difficult task for an experienced medic with a trained eye, regardless of the era of history he may belong to. But to accurately describe a cluster of cells measuring not more than 0,1 millimetre and the exact timing of its structuring is a feat which doesn´t seem to be possible to be described by a caveman.

The Vedas with all the suplementary literatures like the Upaniṣads, Purāṇas or Mahābharata (containing the Bhagavad-gītā) were compiled 5000 years ago. They precede any other scripture in the world and concerning that it was the era of stone age transiting into bronze age with people just discovering the secrets of agriculture or metallurgy and developing basic skills like pottery and writing itself (according to what we are taught in school), their content is simply wondrous.

One can find in them informations about the universe being held together by a force of attraction a.k.a. gravity, sphericity of Earth, the speed of light, motions of the Earth (rotation around the axis and its revolution around the sun), revolution times and distances of other planets in our solar system, (all this in the g Veda), Earth being flattened at the poles as well as the scattered sunlight being the physical cause of blue colour of the sky (Mārkandeya Purāṇa), Śrīmad-Bhāgavatam describes the “seven islands” of the Earth (the continents) long before the Vikings or Columbus set their feet on American soil and what to speak of discovering the Australia or Antarctica which had to wait for the westerners until the 17th and 19th century respectively. Hippies will be happy to know that the Bṛhat-samhitā explains how a rainbow forms due to the multicolored sunrays splitting in clouds and even such concept as relativity of time proposed only many centuries later by professor Albert Einstein (an inspired reader of the Bhagavad-gītā btw) is to be found in the Vedas. I don´t wish to continue this enumeration as it may cause diversion from the main topic of this article.

So far other revealed scriptures, or those which are supposed to be revealed, are concerned, the Bible doesn´t really give any significant information on the development of a human within the womb, while the Quran is more advanced in this context. It is mentioned there that the man develops in stages in the womb and it also describes these stages:

“He makes you in the wombs of your mothers in stages, one after another, in three veils of darkness.” (Sura 39:6)

“Then We developed the semen into a leech (note: just like a leech attaches itself to the body of its host, so the embryo attaches itself to the wall of the uterus to receive nourishment). Then We developed the leech into a lump. Then We developed the lump into bones. Then We clothed the bones with flesh. (note: here is the correct description of bones coming before the muscles). Then We produced it into another creature. Most Blessed is Allah, the Best of Creators.” (Sura 23.14)

This is just to show a little example, in fact, the Quranic account of the embryonic development is quite impressive. Yet it does not go into details of such a minuscule structures like cell formations which we will see described in the Śrīmad-Bhāgavatam.

In the West the science of embryology was not exactly developed until the invention of microscopes (the earliest ones in the 17th century) and it really took shape only in the recent 120 years. It is therefore a legit question, how could Śrīla Vyāsadeva 5000 years ago have informations which allowed him to exactly describe the stages of human embryo from the first phase such as fertilization of the ovum by a sperm.

Dr. Keith L. Moore, PhD from the Department of Anatomy, University of Toronto gives this short summary of the evolution of embryology in the West:

“We do not know when it was realized that human beings underwent development in the uterus (womb), but the first known illustration of a fetus in the uterus was drawn by Leonardo da Vinci in the 15th century. In the 2nd century A.D., Galen described the placenta and fetal membranes in his book “On The Formation of the Foetus.” Consequently, doctors in the 7th century A.D. likely knew that the human embryo developed in the uterus. It is unlikely that they knew that it developed in stages, even though Aristotle had described the stages of development of the chick embryo in the 4th century B.C. The realization that the human embryo develops in stages was not discussed and illustrated until the 15th century.

After the microscope was discovered in the 17th century by Leeuwenhoek descriptions were made of the early stages of the chick embryo. The staging of human embryos was not described until the 20th century. Streeter (1941) developed the first system of staging which has now been replaced by a more accurate system proposed by O’Rahilly (1972).” see

As in many other cases and dragging up until today, the idea of western “scholars” was rather a humorous imagination without any basis in reality:

“As recently as the 18th century, the prevailing notion in western human embryology was preformation: the idea that semen contains an embryo – a preformed, miniature infant, or homunculus – that simply becomes larger during development.

Until the birth of modern embryology through observation of the mammalian ovum by von Baer in 1827, there was no clear scientific understanding of embryology. Only in the late 1950s when ultrasound was first used for uterine scanning, was the true developmental chronology of human fetus available.

The competing explanation of embryonic development was epigenesis, originally proposed 2,000 years earlier by Aristotle.

According to epigenesis, the form of an animal emerges gradually from a relatively formless egg. As microscopy improved during the 19th century, biologists could see that embryos took shape in a series of progressive steps, and epigenesis displaced preformation as the favoured explanation among embryologists.” see

Let us now take a dip into the depths of Purāṇic evidence on embryonic development which in detail and precision precedes any other such account in the known human history. The following are the verses of Śrīmad-Bhāgavatam´s 3rd Canto 31st Chapter entitled Lord Kapila’s Instructions on the Movements of the Living Entities translated from sanskrit language by His Divine Grace A.C. Bhaktivedanta Swami Prabhupāda.


śrī-bhagavān uvāca

karmaṇā daiva-netreṇa jantur dehopapattaye

striyāḥ praviṣṭa udaraṁ puṁso retaḥ-kaṇāśrayaḥ

śrī-bhagavān uvāca—the Supreme Personality of Godhead said; karmaṇā—by the result of work; daiva-netreṇa—under the supervision of the Lord; jantuḥ—the living entity; deha—a body; upapattaye—for obtaining; striyāḥ—of a woman; praviṣṭaḥ—enters; udaram—the womb; puṁsaḥ—of a man; retaḥ—of semen; kaṇa—a particle; āśrayaḥ—dwelling in.


“The Personality of Godhead said: Under the supervision of the Supreme Lord and according to the result of his work, the living entity, the soul, is made to enter into the womb of a woman through the particle of male semen to assume a particular type of body.”

In the first śloka (verse) of this Bhāgavatam chapter we see the description of a sperm cell (puṁso retaḥ-kaṇāśrayaḥ: puṁsaḥ—of a man; retaḥ—of semen; kaṇa—a particle) as the agent of procreation, entering the womb of the mother. People naturally must have had the notion that male semen and its discharge into woman´s womb is the cause of pregnancy, but the idea that semen contains “particles” couldn´t be conceived without an instrument to enhance the power of the scientist´s insufficient vision. In the West such knowledge was not revealed until the 17th century.

“The person with the dubious honor of being the first to study sperm in detail was Anton van Leeuwenhoek, a Dutchman who developed the early compound microscope. Van Leeuwenhoek first used his new tool to examine more chaste subjects such as bee stingers, human lice and lake water in the mid-1670´s.

Colleagues urged him to turn his lens to semen. But he worried it would be indecent to write about semen and intercourse, and so he stalled. Finally, in 1677, he gave in. Examining his own ejaculate, he was immediately struck by the tiny “animalcules” he found wriggling inside.

Hesitant to even share his findings with colleagues van Leeuwenhoek hesitantly wrote to the Royal Society of London about his discovery in 1677. If your Lordship should consider that these observations may disgust or scandalise the learned, I earnestly beg your Lordship to regard them as private and to publish or destroy them as your Lordship sees fit.”

His Lordship (aka the president of the Royal Society) did opt to publish van Leeuwenhoek’s findings in the journal Philosophical Transactions in 1678—thus begetting the brand new field of sperm biology.” see

Amusing history, indeed. A bit disturbing, though, is the “cognitive filter” immediately applied on a startling discovery by it´s own author. On top of that, His “Lordship” was obviously at liberty to conceal or even destroy the new information in case he´d find it “disgusting” or “scandalous” for the “learned”. Fortunately enough for the western civilization, his Lordship evaluated the discovery as beneficial for advancement of knowledge and published it.

For those who would like to suggest, that the translator of these verses makes meanings up to somehow fit an agenda of: “See here? It´s in our scripture since a long time ago!” on the modern scientific knowledge I humbly submit here just a few reviews by Sanskrit scholars, acknowledging the bona-fides of Śrīla Prabhupada´s translations:

“The original version of this work is by Swami Bhaktivedanta.  Essentially, it consists of a commented translation of the Bhagavad-gītā, edited in English, a language which the Swami has completely mastered, as he has Sanskrit and Bengali.” (Olivier Lacombe, Professor, Sanskrit and Indology, Sorbonne University, Paris; Director, Institute of Indian Civilization, Paris )

“The gates of these most valuable treasures of Indian literature were thrown open by His Divine Grace A. C. Bhaktivedanta Swami Prabhupada by his establishing the Bhaktivedanta Book Trust and founding the International Society for Krishna Consciousness with centers in all parts of the world.  The BBT has already published a number of important books written by him on the tradition of bhakti yoga coming down from the hoary Vedic Age to recent times, such as Śrīmad Bhāgavatam and Śrī Chaitanya Charitamrita.  The book production of these encyclopedic renderings is of a very high order, not only in respect of the external get-up and printing, but also in respect of the authenticity of the English translation of the original Sanskrit texts, accompanied by Roman transliterations, vocabularies, detailed cultural expositions of the stanzas, aids to reading of Sanskrit and copious indexes, all of which will serve to make even the common non-Sanskritist readers enjoy these inspiring literary expressions of ancient Indian civilization.  I would therefore recommend that these books be acquired by all college and University Libraries, for they reflect the highest peak of literary genius.”  (Dr. V. V. Gokhale, B. A. (Hon), D. Phil (Indology, Sinology and Philosophy – Bonn; Thirty-seven years as Prof. of Sanskrit, Fergusson College, Pune)

“We must thank the Bhaktivedanta Book Trust for giving us this significant text which is one of the great books of humanity.  This edition is doubly beneficial because in addition to the translation of the Sanskrit text, there is A.C. Bhaktivedanta Swami’s masterful verse-by-verse commentary… Let us hope for a wide distribution of this commented translation of the Bhagavat Purana.  Those who are interested in the living India will find herein the genuineness of an authorized spiritual tradition while having access to one of the most beautiful religious poems in the timeless Hindu tradition.”(Professor Jean Varenne, Dept. of Sanskrit and Indian Studies, Universite de Provence, Aix-en-Provence, France)

“I am most impressed with A.C. Bhaktivedanta Swami Prabhupada’s scholarly and authoritative edition of Bhagavad-gītā.  It provides a clear script of the Devanagari stanzas, beautifully presented with Roman transliteration, precise word-for-word equivalents and lucid English translation followed by an outstanding and comprehensive exegesis, with extensive subject index.” (Dr. Samuel D. Atkins, Professor of Sanskrit and Vedic, Philology, Princeton University)


kalalaṁ tv eka-rātreṇa pañca-rātreṇa budbudam

daśāhena tu karkandhūḥ peśy aṇḍaṁ vā tataḥ param

kalalam—mixing of the sperm and ovum; tu—then; eka-rātreṇa—on the first night; pañca-rātreṇa—by the fifth night; budbudam—a bubble; daśa-ahena—in ten days; tu—then; karkandhūḥ—like a plum; peśī—a lump of flesh; aṇḍam—an egg; vā—or; tataḥ—thence; param—afterwards.


“On the first night, the sperm and ovum mix, and on the fifth night the mixture ferments into a bubble. On the tenth night it develops into a form like a plum, and after that, it gradually turns into a lump of flesh or an egg, as the case may be.”

And here it gets really interesting. On the fifth night the mixture of sperm and ovum (which was also not known in the west until the 19th century) ferments into a BUBBLE. Sounds funny… a bubble. Well, a “bubble” indeed forms exactly five days after conception and that bubble is called a blastula.

“The blastula (from Greek βλαστός (blastos), meaning “sprout”) is a hollow sphere of cells, referred to as blastomeres, surrounding an inner fluid-filled cavity called the blastocoele formed during an early stage of embryonic development in animals.

In humans, blastocyst formation begins about 5 days after fertilization, when a fluid-filled cavity opens up in the morula, a ball of cells. The blastocyst has a diameter of about 0.1–0.2 mm and comprises 200–300 cells following rapid cleavage (cell division). see

How on earth could people observe a “bubble” of 0,1-0,2 millimetres in size within the womb of the to be mother? And what to speak of having an idea, that the object is hollow inside… It would be very interesting to hear an explanation of these descriptions which date thousands of years back. And even if you do not accept the history of Vedas as being compiled 5000 years ago (as some people with poor fund of knowledge claim), still they precede in age any sort of an instrument capable to identify this cell formation.


In the course of a month, a head is formed, and at the end of two months the hands, feet and other limbs take shape. By the end of three months, the nails, fingers, toes, body hair, bones and skin appear, as do the organ of generation and the other apertures in the body, namely the eyes, nostrils, ears, mouth and anus.

This is a description from a medical website:

  • Weeks 9–12: The fetus reaches approximately 8 cm. (3.2 in.) in length; the head is approximately half the size of the fetus. External features such as the face, neck, eyelids, limbs, digits, and genitals are well formed. The beginnings of teeth appear, and red blood cells begin to be produced in the liver. The fetus is able to make a fist.


Within four months from the date of conception, the seven essential ingredients of the body, namely chyle, blood, flesh, fat, bone, marrow and semen, come into existence. At the end of five months, hunger and thirst make themselves felt, and at the end of six months, the fetus, enclosed by the amnion, begins to move on the right side of the abdomen.

This is a description from a medical website:

  • Weeks 16–20: The fetus reaches approximately 20 cm. (8 in.) in length. Lanugo begins to cover all skin surfaces, and fat begins to develop under the skin. Features such as finger and toenails, eyebrows, and eyelashes appear. The fetus becomes more active, and the mother can sometimes begin to feel fetal movements at this stage. see

Descriptions of the embryo thus continue up to the point of delivery. These verses show us the weight of the Vedic scriptures, their authority and depth. Knowledge which took us thousands of years to be discovered by the ascending process of experiment, observation etc., is already there in the śāstra. That knowledge is perfect, because it emanates from the all-perfect Supreme Lord, Śrī Kṛṣṇa. It is His energies that work in these wonderful ways and He Himself, in the form of Śrīla Vyāsadeva, exposes these intricate details. If we see the precision and clarity of explanations concerning things which are already in our experience, thanks to “modern science”, then why waste time and not accept the vedic conclusions on phenomena beyond our experience? That is the way of an intelligent man.
