Atreya wrote nothing down. Six of his pupils each wrote their own version of what he taught, an assembly judged one of them best, and that verdict is why Indian medicine looks the way it does
Six men sat through the same teaching and each went away and wrote his own book about it. Then, as the Charaka Samhita tells it in its opening chapter, they read their treatises before an assembly of physicians and sages, who heard all six and judged Agnivesha’s the best.
Agnivesha’s became the text that Charaka later redacted, that Dridhabala completed centuries after that, and that is still the set book in every Ayurvedic college in India. The other five went quiet.
One classroom’s notes became a canon, because a committee preferred the handwriting of one man in the room.
The Charaka Samhita is built as a dialogue in which he answers questions put to him, sometimes at length and sometimes sharply. There is no way to get behind that to the man, because the recording is all there is.
Tradition makes him the son of the sage Atri and a pupil of Bharadvaja, and associates him with Taxila. The dates offered for him run from around 1000 BC to the sixth century BC, which is a way of saying nobody knows.
The five that lost were not wrong. They were different accounts of the same teaching, and the differences are exactly what a historian wants.
That is not a theoretical point. Bhela’s book, alone of the five, partly survives, and because it was written at the same time as Agnivesha’s it works as a second witness. Scholars use it to separate what Agnivesha originally wrote from what Charaka added and from what Dridhabala added later still. Without a second version of the same lectures, the layers in the Charaka Samhita would be almost impossible to pull apart.
Bhela also uses terms, comparisons and details that are simply not in the other book, and he refers often enough to Gandhara that he is generally taken to have worked there.
The winning book was not a transcript either. Agnivesha wrote up his teacher in his own arrangement and his own words, and every later hand changed it again. What the assembly approved was one man’s editorial judgement about what mattered in what he had heard.
What happened to the other five
Jatukarna’s treatise was still in circulation in the eleventh century. The commentator Chakrapani quotes from it freely, more often than he quotes Bhela. It survived something like fifteen hundred years and then stopped, and no copy is known.
Parashara and Ksharapani are names with no books attached. There is a Harita Samhita in circulation, but scholars generally treat it as a later work written under an old and respectable name rather than the disciple’s.
Bhela came through on a single palm-leaf manuscript in Telugu script, damaged and incomplete, in the palace library at Thanjavur, which the University of Calcutta published in 1921. One further page of it turned up in East Turkestan and sits in a library in Berlin.
An entire school of medicine now amounts to one damaged bundle in Tanjore and a single sheet four thousand kilometres away.
What he actually taught
The doctrine credited to him is the framework the whole system still runs on: the three doshas, the five elements, and internal medicine as a discipline in its own right rather than an appendix to surgery.
The more interesting inheritance is the method. In the text his students preserved, Atreya is argued with. Positions are put against him, he answers them, and the objections are kept in the book instead of being tidied away. A tradition that wanted a guru issuing verdicts would have edited those out.
His pupils recorded the disagreements as carefully as the conclusions, which tells you what kind of classroom it was.
The margin
Strip away the reverence and the shape of this is a near miss. A teacher who published nothing. Six versions of his teaching, of which one was preferred by a committee whose reasoning is not recorded. Four of the rest gone completely, one hanging on by a thread in a south Indian palace library.
It is worth holding both halves of that. The book that won is a very good book, argued over and improved by capable people for two thousand years, and its survival is not an accident of luck alone. It is also true that we hear this teacher through one pupil, and cannot check him against the five who heard the same words.
What we call the foundation of Indian medicine is the one set of notes that happened to win the vote and then got copied often enough to survive.
Sage Atreya Punarvasu is the recognized Father of Internal Medicine for his work in systematizing Kayachikitsa (internal medicine) at the University of Taxila.
What is the relationship between Atreya and Charaka?
Atreya was the original teacher. His student Agnivesa wrote the first manuscript, which was much later edited and expanded by Charaka to become the Charaka Samhita.
Where is Taxila located?
Ancient Taxila was located in the Gandhara region, which is in present-day Pakistan, near the capital city of Islamabad.
What are the three Doshas?
They are Vata (Air/Space), Pitta (Fire/Water), and Kapha (Water/Earth). Atreya taught that health is the balance of these three forces.
Why is Atreya’s work considered scientific?
Because he moved away from religious myths and used logical reasoning, direct observation, and clinical case studies to diagnose and treat patients.
