Dukkha

The sentence "life is suffering", offered as the summary of Buddhism, is wrong twice over: it mistranslates the word and it misstates the claim.

The word is wider than "suffering"

Dukkha does include pain, but its reach is much larger, and the tradition itself divides it three ways:

• Ordinary pain (dukkha-dukkha), physical and mental suffering in the plain sense.
• The suffering of change (viparinama-dukkha), the way pleasant things become sources of distress precisely because they do not last. The pleasure is real; its instability is the problem.
• Conditioned unsatisfactoriness (sankhara-dukkha), a subtle, pervasive inadequacy in all conditioned experience, which can never quite deliver lasting contentment because it is never quite stable.

The third is the one the slogan cannot see. It is not the claim that everything hurts. It is the claim that nothing conditioned can be made to satisfy completely, which is compatible with a great deal of ordinary happiness.

The claim is a diagnosis, not a verdict

Dukkha is the first of four truths, and the structure of the four is the structure of a medical case: a symptom, a cause, a prognosis, a treatment. The second truth gives the cause (craving), the third says the condition can end, and the fourth prescribes the path. A statement that comes packaged with "and here is how it is cured" is not pessimism, and the tradition presses the comparison deliberately, casting the Buddha as a physician rather than a prophet of doom.

Reducing all four truths to the first, and the first to "suffering", keeps the diagnosis and throws away the cure, which is exactly the half the tradition thought was the good news.

The main entry notes that the tradition itself casts the Buddha as a physician, and the comparison is worth taking further, since ancient Indian medicine used a structurally identical four-part diagnostic scheme scholars have long suspected shaped how the Four Noble Truths came to be formulated.

Classical Indian medical texts, most fully the Caraka Samhita, describe a standard procedure with four parts: the disease (roga), its cause (roga-hetu), the state of health free from disease (arogya), and the therapy that removes it (bhaisajya). The parallel to the Four Noble Truths, suffering, its cause, its cessation, and the path to cessation, is close enough that scholars including Kenneth Zysk have argued the Buddha and early community deliberately borrowed the framework of contemporary medical practice to present the dharma as a systematic diagnosis and cure.

Whether the borrowing was conscious or reflects a shared intellectual environment is not fully settled, but the parallel reinforces the main entry's point: a proper diagnosis in the medical tradition, as in the Buddhist scheme, is stated in order to be followed by a cause, a prognosis, and a treatment, so stopping at "life is suffering" is like a patient leaving an examination after hearing only the name of the disease, before the doctor explains what causes it, that it can be treated, and how.
