The Four Noble Truths (Sanskrit: catvāri āryasatyāni; Pali: cattāri ariyasaccāni) are the truths of the Noble Ones, which express the basic orientation of Buddhism: this worldly existence is fundamentally unsatisfactory, but there is a path to liberation from repeated worldly existence. The truths are as follows:

1. The Truth of Dukkha is that all conditional phenomena and experiences are not ultimately satisfying;
2. The Truth of the Origin of Dukkha is that craving for and clinging to what is pleasurable and aversion to what is not pleasurable result in becoming, rebirth, dissatisfaction, and redeath;
3. The Truth of the Cessation of Dukkha is that putting an end to this craving and clinging also means that rebirth, dissatisfaction, and redeath can no longer arise;
4. The Truth of the Path Of Liberation from Dukkha is that by following the Noble Eightfold Path—namely, behaving decently, cultivating discipline, and practicing mindfulness and meditation—an end can be put to craving, to clinging, to becoming, to rebirth, to dissatisfaction, and to redeath.

The four truths provide a useful conceptual framework for making sense of Buddhist thought, which has to be personally understood or „experienced.“ Many Buddhist teachers present them as the essence of Buddhist teachings, though this importance developed over time, substituting older notions of what constitutes prajna, or „liberating insight.“

In the sutras the four truths have both a symbolic and a propositional function. They represent the awakening and liberation of the Buddha, but also the possibility of liberation for all sentient beings, describing how release from craving is to be reached.
