The Four Noble Truths (Pali: Cattāri ariyasaccāni, Sanskrit: Catvāri āryasatyāni, Chinese: Sìshèngdì, Thai: อริยสัจสี่, Ariyasaj Sii) are one of the most fundamental Buddhist teachings. They appear many times throughout the most ancient Buddhist texts, the Pali Canon. They are among the truths Gautama Buddha is said to have realized during his experience of enlightenment.
