Dukkha (Pāli दुक्ख; Sanskrit दुःख duḥkha; according to grammatical tradition derived from dus-kha "uneasy", but according to Monier-Williams more likely a Prakritized form of dus-stha "unsteady, disquieted") is a Pali term roughly corresponding to a number of terms in English including suffering, pain, unsatisfactoriness, sorrow, affliction, anxiety, dissatisfaction, discomfort, anguish, stress, misery, and frustration. In Buddhism, the Four Noble Truths on dukkha are taught as the primary means to attain the ultimate aim of nirvana.
In classic Sanskrit, the term duḥkha was often compared to a large potter's wheel that would screech as it was spun around, and did not turn smoothly. The opposite of dukkha was the term sukha, which brought to mind a potter's wheel that turned smoothly and noiselessly. In other Buddhist-influenced cultures, similar imagery was used to describe dukkha. An example from China is the cart with one wheel that is slightly broken, so that the rider is jolted each time the wheel rolls over the broken spot.
Although dukkha is often translated as "suffering", its philosophical meaning is more analogous to "disquietude" as in the condition of being disturbed. As such, "suffering" is too narrow a translation with "negative emotional connotations" (Jeffrey Po), which can give the impression that the Buddhist view is one of pessimism, but Buddhism is neither pessimistic nor optimistic, but realistic. Thus in English-language Buddhist literature dukkha is often left untranslated, so as to encompass its full range of meaning. .
Dukkha was translated as kǔ (苦 "bitterness; hardship; suffering; pain") in Chinese Buddhism, and this loanword is pronounced ku (苦) in Japanese Buddhism and ko (苦) in Korean Buddhism. In Tibetan it is sdug bsngal (སྡུག་བསྔལ་).
Dukkha is the focus of the Four Noble Truths, which state its nature, its cause, its cessation, and the way leading to its cessation. This way is known as the Noble Eightfold Path. Ancient texts, like Cula-Malunkyovada Sutta and Anuradha Sutta, show Siddartha Gautama, the Buddha, as insisting that the truths about dukkha are the only ones he is teaching as far as attaining the ultimate goal of nirvana is concerned.
The Buddha discussed three kinds of dukkha or suffering:
- Dukkha-dukkha (pain of pain) is the obvious sufferings of :
- Viparinama-dukkha (pain of alteration) is suffering caused by change:
- violated expectations
- the failure of happy moments to last
- Sankhara-dukkha (pain of formation) is a subtle form of suffering arising as a reaction to qualities of conditioned things, including the
- the factors constituting the human mind
Dukkha is also listed among the three marks of existence: impermanence (anicca), suffering (dukkha) and not-self (anatta). Dukkha denotes the experience that all formations (sankhara) are impermanent (anicca) - thus it explains the qualities which make the mind as fluctuating and impermanent entities. It is therefore also a gateway to anatta, not-self.
Insofar as it is dynamic, ever-changing, uncontrollable and not finally satisfactory, unexamined life is itself precisely dukkha. The question which underlay the Buddha's quest was "in what may I place lasting relevance?" He did not deny that there are satisfactions in experience: the exercise of vipassana assumes that the meditator sees instances of happiness clearly. Pain is to be seen as pain, and pleasure as pleasure. It is denied that happiness dependent on conditions will be secure and lasting.
In the early texts, the skandhas explain what suffering is. According to Noa Ronkin, "What emerges from the texts ... is a wider signification of the khandhas than merely the aggregates constituting the person. Sue Hamilton has provided a detailed study of the khandhas. Her conclusion is that the associating of the five khandhas as a whole with dukkha indicates that experience is a combination of a straightforward cognitive process together with the psychological orientation that colours it in terms of unsatisfactoriness. Experience is thus both cognitive and affective, and cannot be separated from perception. As one's perception changes, so one's experience is different: we each have our own particular cognitions, perceptions and volitional activities in our own particular way and degree, and our own way of responding to and interpreting our experience is our very experience. In harmony with this line of thought, Gethin observes that the khadhas are presented as five aspects of the nature of conditioned existence from the point of view of the experiencing subject; five aspects of one's experience. Hence each khandha represents 'a complex class of phenomena that is continuously arising and falling away in response to processes of consciousness based on the six spheres of sense. They thus become the five upādānakhandhas, encompassing both grasping and all that is grasped.'"
The Buddha himself on Dukkha
|“||Birth is dukkha, aging is dukkha, death is dukkha; sorrow, lamentation, pain, grief, & despair are dukkha; association with the unbeloved is dukkha; separation from the loved is dukkha; not getting what is wanted is dukkha. In short, the five clinging-aggregates are dukkha.||”|

In Brahmanic sacred literature, the earliest Upaniṣads — the Bṛhadāraṇyaka and the Chāndogya — are believed to predate or coincide with the advent of Buddhism. In these texts' verses, the Sanskrit word duḥkha (translated below as "suffering" and "distress") occurs only twice. In the Bṛhadāraṇyaka Upaniṣad, it states (in English and Sanskrit):
While we are still here, we have come to know it [ātman].
ihaiva santo 'tha vidmas tad vayaṃ na ced avedir mahatī vinaṣṭiḥ
In the Chāndogya Upaniṣad is written:
When a man rightly sees,
na paśyo mṛtyuṃ paśyati na rogaṃ nota duḥkhatām
Thus, as in Buddhism, in these sacred texts the eradication of duḥkha is a desired and promised outcome; here duḥkha serves as an antipode to the ultimate Brahmanic goal of immortality (amṛtās). In addition, as in Buddhism, one overcomes duḥkha through the development of a transcendent understanding. Nonetheless, in these Brahmanic sacred texts, duḥkha is either identified as a general condition or as simply one of many undesirable states, not embodying the conceptual centrality assigned to it in Buddhism's Pali Canon.
