The Medicine

13. The Four Tantras

rgyud bzhi (gyü-shi) — “the Four Tantras”. The foundational medical text, in continuous use from the 12th century to the present.

The medical tradition is called gso ba rig pa (sowa rigpa), “the science of healing” — and is officially one of the five great knowledges.

The four parts

1. Root — synopsis; the image of the three trees
2. Explanatory — anatomy, physiology, embryology, dietetics
3. Instructional — the most extensive; nosology and treatments
4. Subsequent — pulse, urine, pharmacology, external treatments

The disputed origin

The traditional position: taught by the Buddha in the form of the Medicine Teacher, and translated from Sanskrit.

The scholarly position: composed or redacted in Tibet by Yuthok Yönten Gönpo the Younger (1126–1202), from multiple sources.

And what is noteworthy: the dispute is internal. Tibetan scholars argued already long ago that the text is a Tibetan composition and not an Indian revelation — a position with heavy cost, because it undercut its prestige.

What they synthesised

Here is what is really interesting:

Uroscopy — the detailed examination of urine as a main diagnostic tool — is a signature of Galenic-Islamic medicine and not of Indian. Its presence is one of the strongest indications of Western influence.

And the Tibetan medical histories themselves name foreign physicians invited to the court in the 8th century, among them names that point to the Greek tradition.

The paintings

In the 17th century, the regent Desi Sangye Gyatso commissioned 79 painted panels (thangka) illustrating the entire medical system: anatomy, embryology, medicinal plants, surgical instruments, pulse types, stages of decomposition.

They are, in essence, a visual medical encyclopaedia — and one of the most impressive educational tools produced by any pre-modern medicine.

In 1696 the medical school of Chakpori was founded in Lhasa. In 1916 the Men-Tsee-Khang.

14. The three nyes pa

nyes pa (nyepa) — literally “defect, fault, injury”. Not “humour”.

The word is important: these are named not as constituents but as problems. They are the three principles that, when deranged, produce every illness.

The critical peculiarity

Note where the mind goes: into rlung.

Tibetan medicine has no separate chapter of psychiatry. Psychic disturbance is, in the overwhelming majority, a disturbance of wind — that is, a somatic condition with psychic symptoms, treated with food, heat, oil and regulation.

This is the most directly applicable idea in the whole document, and it returns in chapter 16.

The three roots and the nine branches

The first tantra organises everything into an image of a tree with three roots:

1. The root of physiology and pathology — what is health and what is illness
2. The root of diagnosis — observation, palpation, questioning
3. The root of treatment — diet, behaviour, medicines, external treatments

The order of treatment — and it is clear

First diet. Then behaviour. Then medicines. Last, interventions.

Medicine is not given if the first two have not been tried. And the first two are not supplementary — they are the main treatment.

15. Pulse and urine

The diagnostic technology, and it is impressively standardised.

The pulse

The physician places three fingers on the radial artery of each wrist. Each finger “reads” different organs, and each finger reads at two depths — superficial (hollow organs) and deep (solid organs).

The preconditions are strict and explicitly recorded:

• The patient must not have eaten — the examination is done at dawn
• The previous day they should have avoided alcohol, heavy food, intense exercise, sexual activity, strong emotion
• The physician must also be sober and calm

This is not ritual. It is control of variables — recognition that the signal is sensitive to noise.

The urine

Examined at dawn, from the first urination, in a white container, in natural light. Recorded:

Colour · steam (how much and how long) · smell · bubbles (size, duration) · suspended particles · surface film

And the characteristic: the sample is stirred with a stick and observed as it changes while cooling — in three phases, hot, warm, cold.

The honest assessment

What stands: the methodological rigour (standardised conditions, control of confounders), the systematic recording, and the fact that certain findings in urine have real diagnostic value — smell in diabetes, colour in jaundice, foam in proteinuria.

What does not stand: the correspondence of specific fingers with specific organs has no anatomical basis, and the reproducibility of the fine pulse distinctions between different examiners has not been documented.

16. Srog rlung: the illness of excessive practice

This is the chapter for which the document was written.

srog rlung (sok-lung) — “vital wind”, or more precisely the disturbance of the wind that holds life.

And the critical thing: this is not a warning. It is a diagnostic category, in a medical textbook, with aetiology, symptomatology and therapeutic protocol.

The symptoms

As recorded:

• Anxiety, restlessness, sense of impending catastrophe
• Palpitation, awareness of the heartbeat in the chest
• Tightness or pain in the sternum and between the shoulder blades — the most characteristic
• Insomnia, light and agitated sleep
• Galloping, uncontrollable thought
• Dizziness, buzzing, sensation of a lump in the throat
• Frequent sighs
• Sadness without cause, irritability, crying
• Loss of appetite, dryness

The causes — and here is the striking thing

The texts name explicitly, among the causes:

• Excessive or wrongly performed meditation
• Much solitary practice without adequate support
• Intense breath work
• Grief, shock, loss
• Overwork, insomnia
• Insufficient or too light food
• Cold, wind, dryness
• Excessive speech and excessive thought

That is: the tradition records the damage from its own practice as a recognised occupational risk, and trains physicians to treat it.

Not many systems do this.

The treatment — and it is counter-intuitive

The protocol goes against what a Westerner would assume:

1. Heavy, fatty, nourishing food. Bone broth, meat, butter, dark sugar, garlic, nutmeg, warm milk. Not a light diet, not fasting, not cleansing.

2. Heat. Warm room, warm drinks, do not let the back get cold.

3. Oil. Massage with warm oil, especially the back and the scalp.

4. Company. Explicitly: do not let them stay alone. Calm human company.

5. Quiet, darkness, sleep.

6. And most important: reduction or cessation of practice.

Sometimes moxibustion at points on the upper back is added.

Why it matters today

First, there is contemporary clinical literature. Srog rlung has been studied in Tibetan refugee populations, where it correlates with experiences of trauma and displacement, and its symptomatology overlaps significantly with generalised anxiety, panic attacks, and post-traumatic manifestations.

Second, the literature on adverse effects of meditation has recorded, in Western practitioners, a very similar set: anxiety, insomnia, hyperarousal, depersonalisation — especially after intensive practice in isolation.

Third, and the most useful: the principle.

If the practice produces anxiety, palpitation and insomnia, the problem is not your resistance. The problem is the practice.

And the answer is not more discipline, more fasting or more isolation. It is food, heat, sleep, human company, and less practice.

It is one of the few times a tradition explicitly prescribes less of itself.

This chapter has its own companion essay on this site: The Tradition That Diagnosed Its Own Damage, which reads srog rlung against the modern meditation-adverse-effects literature.
