Introduction of Non-Buddhist Medical Traditions in Tibet
The earliest medical system in Tibet was the pre-Buddhist one of Bon, going back to at least a thousand years before the common era. Its medical literature is preserved in the four Bonpo medical texts, called The Four Hundred Thousands (‘Bum-bzhi) and studied as part of the training for the Geshe degree at Bonpo monasteries. Some of its terminology and approaches have survived into the modern Buddhist system.
The next period began in the mid-fifth century AD, when two physicians came from South India during the reign of the twenty-eighth Yarlung king of Central Tibet, Lhatotori Nyentsen (Lha-tho-tho-ri gNyan-btsan). One of them married the king’s daughter and their descendants became the court physicians. It was during the reign of this king that the first Buddhist texts came to Tibet from India.
Since the title of this first doctor was “biji,” which is the Sogdian word for doctor, it is possible to conjecture that this physician had some connection with the region of Sogdia, located in what is nowadays Uzbekistan. During this period, Sogdian merchants and cultural influences were commonly found throughout Central Asia, particularly along the Silk Route from India to China. But since Sogdian was the international language of commerce for the entire area, it is also possible that the Sogdian word for doctor was used generically throughout the region, much as the Mongolian word for doctor, “emchi,” has been used in more modern times to denote a doctor. It is difficult to know exactly what tradition of medicine this line of “biji” practiced.
The main events that shaped the development of the Tibetan Buddhist system occurred during the rule of Emperor Songtsen Gampo (Srong-btsan sgam-po) in the early to mid-seventh century. This was the great Yarlung king who founded the Tibetan Empire, stretching from northwestern China nearly to Afghanistan, to Nepal and to northern Burma, and who had sent his minister, Tonmi Sambhota (Thon-mi Sambhota), to Khotan to develop a writing system for Tibet, though the minister adapted it in Kashmir on his way there. This emperor had both a Chinese and a Nepalese princess as his wives. The former one brought with her from China several texts on Chinese medicine and astrology, which were translated into Tibetan.
Emperor Songtsen Gampo invited to his court physicians from the three major medical traditions of the time. These were the Hindu Ayurvedic system of India, the classical Chinese tradition and the ancient Greek system. This latter came from Tazik and Rome. “Tazik” refers to the Persian world, including modern-day post-Soviet Central Asia and Afghanistan, Sogdia as well. It is also the name of the land where the founder of the Bon tradition, Tonpa Shenrab Miwo (sTon-pa gShen-rab Mi-bo), came from, according to traditional Bonpo sourcees. “Rome” refers to the Eastern Roman or Byzantine world, including the Arab regions. The ancient Greek medical system had survived in these areas from the time of the conquests of Alexander the Great. There were also physicians of the shamanic system of medicine of Mongolia, which was ruled at that time by the Northern Turk Khaganate.
The representatives of each of the three major systems translated some of their own texts and compiled together in Tibetan a seven-volume work on medicine. The Greeks specialized in operations and dissection, and at first it was their system that was favored. The Greek physicians were kept at court, while the Chinese and Indians were sent home. A code similar to the ancient Greek Hippocratic oath was adapted that emphasized treating the poor, having doctors come from simple families and following an altruistic code of ethics.
During the second half of the eighth century, Emperor Tri Songdetsen (Khri Srong-lde-btsan, Trisong Detsen) invited once more to Tibet physicians from these same three traditions, as well as from Nepal. They came from as far away as Persia, the Arab Caliphate and Byzantium, as Tibet in those days had contact with all of them. Tri Songdetsen was the famous emperor who had briefly conquered the Chinese capital and under whom the Tibetan Empire included the Tarim Basin of East Turkistan as well as many of the mountainous areas of West Turkistan. He is remembered for having invited Shantarakshita and then Guru Rinpoche Padmasambhava from India to Tibet to establish Indian Buddhism. These doctors compiled together some more medical texts and trained a number of Tibetan physicians.
Introduction of the Indian Buddhist Medical Tradition
It was at this time that the Indian Buddhist medical tradition came to Tibet as well. It was introduced from Kashmir by Vairochana, the famous early translator of Buddhist texts, who translated, as well, the Four Medical Tantras (sMan-gyi rgyud-bzhi), which he had studied from the Kashmiri physician Chandranandana. The word “tantra” means an everlasting stream of continuity. Medicine is called a “tantra” because there is the everlasting stream of continuity of the basis, namely the continuity of subtlest consciousness and subtlest energy; the everlasting stream of the path, namely proper health preserving proper physical, verbal and mental behavior; and the everlasting stream of the result, namely the total good health on all physical, verbal, mental and emotional levels of a fully enlightened Buddha.
The Four Medical Tantras are the Root Tantra (rTsa-rgyud), Explanatory Tantra (bShad-rgyud), Quintessence Tantra (Man-ngag rgyud) and Further Tantra (Phyi-ma’i rgyud). According to tradition, they are traced to the Buddha who, in the form of the Medicine Buddha, Bhaishajyaguru, taught them, at age seventy-one, in his palace in the city of Tanadug (lTa-na-sdug). These four tantras deal with eight branch topics:
- The body, which includes anatomy, physiology, embryology and pharmacology
- Diseases from harmful spirits
- Fertility and reproduction.
This is slightly different from the eight branches of the Ayurvedic system, which omit gynecology and the treatment of wounds, and include instead surgery and diseases of the head and neck.
Just as there was held at Samye (bSam-ye) Monastery a debate to decide whether the Indian or Chinese form of Buddhism would be adopted in Tibet, likewise a similar conference was held at the same monastery to determine the system of medicine to be used. Just as Indian Buddhism was declared the winner, likewise it was decided that the Indian Buddhist medical system would form the major framework for Tibetan medicine.
Yutog the Elder and Yutog the Younger
In the early ninth century, the great Tibetan master physician, Yutog the Elder (g.Yu-thog rnying-ma Yon-tan rgya-mtsho) traveled three times to India and once to China to study with physicians there. Afterwards, he slightly rewrote the Four Medical Tantras, including within them material that came from the Hindu Ayurvedic, Chinese, Greek and Bon systems that had been used in an eclectic fashion in Tibet prior to this. This style of taking certain aspects from the teachings of these different cultures, reworking, combining and making advances on them to derive a unique Tibetan system occurred with the development of Tibetan astrology as well. Thus, aspects are found in Tibetan medicine that are reminiscent of features in the Hindu, Chinese and ancient Greek systems, but which are defined and used in quite different ways, as with the example of the eight branch topics just mentioned.
Yutog the Elder also founded the first Tibetan medical college, Tanadug (lTa-na-sdug), in Kongpo Melong (Kong-po Me-long) and wrote an eighteen-chapter commentary to the Four Tantras. Guru Rinpoche Padmasambhava, the great Nyingma master, then concealed Yutog the Elder’s compilation of the Four Medical Tantras at Samye Monastery, where they remained hidden for several centuries during which the times were considered unconducive for their practice. Guru Rinpoche also hid as “treasure texts” (gter-ma, terma) many Buddhist manuals of this Old Translation Period as well.
The famous New Period translator, Rinchen Zangpo (Rin-chen bzang-po), during the first half of the eleventh century, translated further Buddhist medical texts from Kashmir and founded a medical school at Toling (Tho-ling) Monastery in Western Tibet. This was the monastery that soon afterwards hosted the Indian master Atisha, who had been to Indonesia and from whom the Kadam tradition of Buddhism is traced.
The texts of Yutog the Elder were recovered in 1038 by Drapa Ngonshe (Gra-pa mNgon-shes) and eventually were transmitted to Yutog the Younger (g.Yu-thog gsar-ma Yon-tan mgon-po) in the twelfth century. This great physician re-edited the Four Medical Tantras in their present form of 156 chapters, written in the style of questions and answers between two sages. This, with its commentaries, forms the basis of all Tibetan medicine.
The number 156 is significant since it is the number of side channels that come from the six chakras according to the Kalachakra system. Together with the six chakras, 162 is the traditional number of verses in the seminal Kalachakra text, A Chorus of Names of Manjushri (‘Jam-dpal mtshan-brjod, Skt. Manjushri-nama-samgiti), minus the five verses of the epilogue. This text had already been translated into Tibetan during the time of Emperor Tri Songdetsen. The Kalachakra teachings were introduced to Tibet in 1027. It’s difficult to ascertain, however, the influence of the Kalachakra teachings on Tibetan medicine at this early stage.
Yutog the Younger also composed Quintessential Drop Teachings of Yutog (g.Yu-thog snying-thig), a set of Nyingma rituals used for the consecration of Tibetan medicines even today.
Development of the Medical Traditions in Tibet
In the early fourteenth century, the Third Karmapa, Rangjung Dorje (Rang-byung rdo-rje), wrote commentaries to the Abridged Glorious Kalachakra Tantra, Stainless Light (dPal dus-kyi ‘khor-lo’i bsdus-don dri-ma med-pa’i ‘od). From his commentary on the first chapter, An Adornment to Clarify the Manner of “The Abridged Kalachakra Tantra, Stainless Light” (dPal dus-kyi ‘khor-lo’i bsdus-don dri-ma med-pa’i ‘od-kyi tshul gsal-bar byed-pa’i rgyan) is derived the Tsurpu (mTshur-phu) tradition of Tibetan astrology. From his work on the second chapter, The Meaning of the Profound “Internal (Kalachakra” Chapter of “Stainless Light”) that Gathers Together the Essence of Oceans of Anuttarayoga Tantras (rNal-'byor bla-na med-pa'i rgyud-sde rgya-mtsho'i snying-po bsdus-pa zab-mo nang-gi don) are derived various aspects that were elaborated upon and incorporated into the Tibetan medical system. Thus, from this point onwards, certain anatomical and terminological features dealing with the body’s subtle energy channels are adapted from the Kalachakra system. Also derived from the Kalachakra system are the formulas for the compilation of various medicines from precious gem substances and particularly for compounding detoxified mercury. Further, the Kalachakra Buddha-figure, together with its interwoven ten-syllable symbol, became associated from this time with both Tibetan medicine and astrology.
In the fifteenth century there developed two medical lineages, the Chang (Byang-lugs) and the Zur (Zur-lugs), founded by Changpa Namgyal Dragzang (Byang-pa rNam-rgyal grags-bzang) and Zurkar Nyamnyi Dorje (Zur-mkhar mNyam-nyid rdo-rje) respectively. The former wrote commentaries to and put special emphasis on the first two of the Four Medical Tantras, while the latter wrote commentaries to all four. They differ slightly in their descriptions of some aspects of the subtle energy system, on the preparation and ingredients of certain medicines, on the use of enemas, on the detoxification process for mercury and on certain moxabustion points.
The Fifth Dalai Lama (rGyal-ba lnga-pa chen-po Ngag-dbang blo-bzang rgya-mtsho) was a great patron of Tibetan medicine during the second half of the seventeenth century. His prime minister, Desi Sanggye Gyatso (sDe-srid Sangs-rgyas rgya-mtsho), who also ruled as regent after the Dalai Lama’s death, wrote texts on both medicine and astrology, called respectively Blue Aquamarine (Baidurya sngon-po) and White Aquamarine (Baidurya dkar-po). He combined the Chang and Zur traditions and founded the Chagpori (lCags-po-ri) Medical College for monks at Lhasa.
Under the Thirteenth Dalai Lama (rGyal-ba Thub-bstan rgya-mtsho), during the early part of the twentieth century, the present system of four levels of medical degrees was instituted, as well as a standard medical examination system. This was parallel to the restructuring he initiated in the monastic education system for the Geshe degree in Buddhist philosophy. His personal physician, Kyenrab Norbu (mKhyen-rab nor-bu), founded in Lhasa the Mentsikang (sMan-rtsis khang), the Tibetan Government Medical and Astro Institute, primarily for monks and Tibetan military men from all over the country. Some special lay students were admitted as well.
Lady doctors were traditionally trained only privately, outside the colleges, and most often within family lineages. In the southeastern Tibetan province of Kham, medicine was studied only privately from individual teachers. In the northeastern Tibetan province of Amdo, there was a tradition of “menpa datsangs” (sMan-pa Grva-tshang) – monastic medical colleges – the most famous being at Labrang Tashikyil (Bla-brang bKra-shis ‘khyil).
Many great Tibetan figures have been masters not only of Buddhist meditation systems, but also of medicine. The most well-known example was Milarepa’s disciple, Gampopa (sGam-po-pa).
There is a tradition in Tibetan monasteries for people to try to master all fields of knowledge and become like what was known in Europe as “Renaissance men.” This would naturally include the subject of medicine. Examples of such masters in the nineteenth century, who were noted for their medical skills among their other accomplishments, were the three great spiritual leaders of the “rimey” (ris-med) non-sectarian movement in the southeastern Tibetan province of Kham, namely Jamyang Kyentse Wangpo (‘Jam-dbyangs mkhyen-brtse’i dbang-po), Ju Mipam (‘Ju Mi-pham) and Jamyang Kongtrul Lodro Taye (‘Jam-dbyangs Kong-sprul Blo-gros mtha’-yas). A more recent example in the twentieth century was the late Junior Tutor of His Holiness the Dalai Lama, Trijang Rinpoche (Khri-byang Blo-bzang ye-shes bstan-‘dzin rgya-mtsho) .
Current Situation in Tibet And India
In 1959, the Chagpori Medical College in Lhasa was destroyed by the Communist Chinese. The activities of the Tibetan Government Medical and Astro Institute were drastically curtailed in that year, and totally stopped during the Cultural Revolution in the late 1960’s. After the death of Mao Tse-tung in 1977, it was re-opened in Lhasa under Chinese control, with women students also admitted. It has been renamed the Medical and Astro Institute of the Tibetan Autonomous Region, with the Chinese claiming that Tibetan medicine is merely a subdivision and variant of Chinese medicine, which is not the case. Of all the aspects of Tibetan culture, Tibetan medicine is the only one that the Communist Chinese have allowed to continue intact. This is because of its great effectiveness in having cured many Chinese officials.
The Tibetan Government Medical and Astro Institute has been continued in the Tibetan refugee community around His Holiness the Dalai Lama in Dharamsala, India. It was restarted in 1962 and, at present, has a seven-year program for training doctors, open to both men and women. It also has, in connection with it, an astrology school with a five-year course, as well as a hospital, an out-patient clinic, a factory for making medicines, a small medical library and a medical museum. At present (1990), it has thirty-four branch clinics around India and Nepal.
Predictions of Diseases of the Future
The Tibetan Government Medical and Astro Institute has a modest research program as well, for instance concerning the diseases of the future predicted in the ancient Tibetan medical texts. In the eighth century, Topon Chokyi Dragpa (Chos-kyi grags-pa) explained eighteen malignant disorders of the future, such as cancer, meningitis, diphtheria and pneumonia, and wrote in detail about their signs of development, symptoms, prevention and treatment. Guru Rinpoche Padmasambhava predicted other diseases, and further ones are mentioned in the Kalachakra Tantra.
The last chapter of the Four Medical Tantras predicts that, in the future, changes in diet and lifestyle, and the use of chemicals, will provide the contributory conditions for new diseases to arise. Air, food and the earth will become polluted. This will foster the growth of micro-organisms that will cause the defense system of the body to weaken and such sicknesses as allergies, asthma, cancer and AIDS to arise. Sicknesses will come even from the sunrays, which implies from other types of radiation as well. These new pollution-induced diseases can often be prevented by proper diet, behavior and lifestyle. They can also be treated by various medicines. Such medicines have been prepared by this Tibetan Medical and Astro Institute according to the guidelines given in these texts and are being tested in India and various countries around the world.
History of Tibetan Medicine in Mongolia
The Tibetan medical system spread from Tibet to Mongolia, both so-called “Outer” and “Inner” Mongolia, and from there northwards to the Buryat Mongol and Tuvinian Turkic regions of Eastern Siberia. It also spread directly from Tibet to the Oirat Mongol regions of East Turkistan, which are in present-day Xinjiang province of China, and to their relatives in Kalmykia, around the northern part of the Caspian Sea, as well as to northern China and Manchuria. It is found as well throughout the Buddhist Himalayan regions from Ladakh eastwards through Lahul, Spiti, Kinnaur, Nepal, Sikkim, Bhutan and Arunachal.
The first translations of medical texts from Tibetan into Mongolian were started during the time of Khubilai Khan, in the mid-thirteenth century. It was at that time that the first translations were made into Mongolian of Tibetan Buddhist texts as well. The Four Medical Tantras were translated in the fourteenth century. Once Tibetan Buddhism had become thoroughly established and widespread throughout the Mongol regions at the end of the fifteenth century with the visit of the Third Dalai Lama, the basic medical texts were retranslated in the early sixteenth century, together with Desi Sanggye Gyatso’s medical works.
The first Tibetan medical school in Mongolia, the Dakhan Emchi Aimak, was founded by the Tibetan physician Dakhan Emchi Lobsang Norbu in 1712. The most famous monastic medical college, the Sorig Shanpan Ling, was started in Urga, present-day Ulaan Baatar, in 1760. Eventually, most of the monasteries in Mongolia, as well as in Buryatia, Kalmykia and Tuva had medical colleges as one of their divisions, where monk doctors were trained. This was in keeping with the tradition of the Amdo province of northeastern Tibet. In fact, Mongolian doctors became so famous that even in Tibet the modern colloquial term for a doctor is the Mongolian borrow-word “emchi.”
The most outstanding Mongol physician was the eighteenth century Mongour master, Sumpa Khenpo Yeshe Paljor (Sum-pa mKhan-po Ye-shes dPal-‘byor), known in Mongolian as Ishbaljor. The Mongours are a Mongolian people living in the northeastern Tibetan province of Amdo and in adjacent Gansu. He composed five medical texts, including one that describes the local medicinal plants that grow in the Mongol regions and which can be used in the pharmacopoeia as substitutes for those found only in Tibet.
In the nineteenth century, the Mongolian physician Jambaldorj wrote in Tibetan a four-volume text with further elaboration on native Mongolian medicinal plants, with all the ingredients and preparation procedures for the various medicines, given in the Tibetan, Mongolian, Manchu and Chinese languages. Mongolia at that time was part of the Manchu Chinese Empire.
Distinctive Features of the Mongolian Tradition
Although, as in all lineages of Tibetan medicine, diseases are classified according to the three humors of wind, bile and phlegm, in the Mongolian tradition there is more emphasis on the discussion of the heat functions of the bodily organs and the classification of sicknesses into hot and cold disorders. This is due to the slight influence found in the Mongolian tradition from Chinese medicine and its classification of diseases as yin and yang. Nevertheless, Tibetan medicine in the Four Medical Tantras does speak in terms of hot and cold disorders. This is not at all alien to the Tibetan system, but just a shift in emphasis.
It should be repeated, then, that Mongolian medicine is not a separate system from the Tibetan one. It is firmly anchored in the Four Medical Tantras, although it has some of its own distinctive aspects, developments and adaptations. For instance, the Mongolian tradition has its own unique form of massage practiced in conjunction with the traditional Tibetan system. When nowadays Chinese acupuncture is practiced in Tibetan medical clinics in Mongolia and Buryatia, and certain herbal medicines from the Chinese system are used, this is an expedient, recent addition made mostly in the 1950‘s due to loss of contact with the Tibetan tradition of acupuncture and Tibetan sources of medicinal plants. It does not indicate that Mongolian medicine is based on or a variety of the Chinese system.
History of Tibetan Medicine in the [Former] Soviet Union, Inner Mongolia and China
Tibetan medicine first came to the Trans-Baikal Siberian Mongol region of Buryatia at the end of the seventeenth century. There were two main traditions, the Khorinsk and Selenga. The Khorinsk tradition came from the monastic medical college of Labrang Tashikyil in the northeastern Tibetan province of Amdo. It followed only Tibetan texts, and its main centers were Sholotu Datsan at Atsagat, and Egetuiski, Aginski and Tsugulski Datsans. The Selenga tradition came from Mongolia, followed both Mongolian and Tibetan texts and, like the Mongolian tradition, had a slight influence from Chinese medicine. Its main centers were Gusino-ozorski, Tsongulski, Sanaga and Yangarzhinski Datsans.
The Caspian Mongol region of Kalmykia, the Siberian Buddhist Turkic area of Tuva, and Inner Mongolia, now incorporated into the People’s Republic of China, also had monastic colleges for Tibetan medicine in their Buddhist monasteries. In Kalmykia, one of the main such colleges was at Emchin Khurul, with many branches at the other monasteries.
In Tuva, the main monastic medical college was at Chadanski Khure. There was a well-developed local tradition of shamanistic herbal medicine in Tuva as well. This system was not mixed, however, with the Tibetan Buddhist one in the monasteries, but co-existed outside.
Tibetan medicine flourished in Imperial Russia in the nineteenth and early twentieth century. Pyotr Badmaev, for instance, a Buryat doctor from Aginski Datsan, was the personal physician of the last Czar of Russia, Nikolai II, as well as of Rasputin. For this reason, Badmaev was officially out of favor until 1985. Czar Nikolai II was the czar who had the Leningrad Datsan, a Tibetan Buddhist monastery, built in St Petersburg.
These medical colleges in Buryatia, Kalmykia, Tuva, and Mongolia were destroyed, along with the Buddhist monasteries in general, during the Stalin era of the late 1930’s. In Inner Mongolia there was also great decline, especially during the Cultural Revolution in the late 1960’s.
In the early eighteenth century, a Tibetan monastic medical college was founded as part of the Yonghegong monastery in Beijing. The Tibetan medical tradition was also found among the Oirat Mongols of East Turkistan, but more research must be done about all of this.
Present Situation in Outer and Inner Mongolia and the Soviet Union
At present (1990) there is an Institute of Traditional Mongolian Medicine in Ulaan Baatar, Mongolia, which mostly continues the tradition of Mongolian massage and is just recently working to revive the rest of the system. There are lineages of private traditional doctors, however, mostly continued at Gandan Thekcholing Monastery in Ulaan Baatar. The government has just recently given permission for the re-establishment of the Sorig Shanpan Ling Medical Monastery, which will train not only monks, but also laymen and women.
In Buryatia, there are also some lineages of private traditional doctors at Ivolginski Datsan near Ulan Ude and at Aginski and Tsugulski Datsans in Chita District, but they are limited in their supply of medicines and very few of them can do pulse diagnosis. There is also much scientific study of Tibetan medicine at the Buryat Institute of Social Studies of the Siberian Branch of the Academy of Sciences of the USSR in Ulan Ude. But the tradition is completely lost in Kalmykia and Tuva.
In Inner Mongolia, the system is more intact and is found at the Medical College of Inner Mongolia in Hohhot and the Scientific Research Center of Mongolian Medicine in Tongliao. The Chinese try to divide the Mongolian and Tibetan systems of medicine and claim they are distinct entities which, as has been seen, is not the case.
This article and the subsequent ones that follow in this section of the Study Buddhism website derive from a series of lectures I delivered in the Soviet Union many years ago. In March 1990, as part of a teaching and research tour of the Soviet Union and Mongolia, I delivered a series of lectures in Moscow at the Library of Medicine of the Ministry of Health of the U.S.S.R. The lectures were organized and co-sponsored by the Center for Traditional Medicine of the Department of Medical Information (Soyuzmedinform) of the Ministry of Health of the U.S.S.R., under the directorship of Dr. Natalia Lukyanova, and the Central Spiritual Board of Buddhists of the U.S.S.R., under the guidance of its Moscow representative, Tom Rabdanov. The lectures were given in English and translated orally into Russian by Andrey Terentyev. Together with revisions and expansions I later made, they were prepared for publication in Russian, under the title Tibetan Buddhism and Culture in Modern Perspective: A Series of Lectures in the Soviet Union, by Slava Komarovskiy, Elena Shelingovskaya and Andrey Terentyev. They will be published by Soyuzmedinform of the Ministry of Health of the U.S.S.R. The present work is a further expansion and reorganization based on that text.
I wish to express my appreciation and gratitude to His Holiness the Dalai Lama and Lodi Gyari Rinpoche for their encouragement in this project. I also wish to acknowledge all the help and information I have received during the course of researching this material from Dr. Natalya Lukyanova, Tom Rabdanov, and Andrey Terentyev in Moscow; the late Most Ven.
