In Buddhism, the Four Noble Truths (चतुरार्यसत्यानि; caturāriyasaccāni; "The Four Arya Satya") are "the truths of the Noble Ones", the truths or realities for the "spiritually worthy ones". The truths are: dukkha ('not being at ease', "suffering," from dush-stha, "standing unstable,") is an innate characteristic of the perpetual cycle (samsara, wandering) of grasping at things, ideas and habits; samudaya (origin, arising, combination; "cause"): dukkha (unease) arises simultaneously with taṇhā ("craving, desire or attachment, thirst). nirodha (cessation, ending, confinement): dukkha can be ended or contained by the confinement or letting go of this taṇhā; marga (path, Noble Eightfold Path) is the path leading to the confinement of tanha and dukkha. The four truths appear in many grammatical forms in the ancient Buddhist texts, and are traditionally identified as the first teaching given by the Buddha. While often called one of the most important teachings in Buddhism, they have both a symbolic and a propositional function. Symbolically, they represent the awakening and liberation of the Buddha, and of the potential for his followers to reach the same liberation and freedom as him. As propositions, the Four Truths are a conceptual framework that appear in the Pali canon and early Hybrid Sanskrit Buddhist scriptures, as a part of the broader "network of teachings" (the "dhamma matrix"), which have to be taken together. They provide a conceptual framework for introducing and explaining Buddhist thought, which has to be personally understood or "experienced". As a proposition, the four truths defy an exact definition, but refer to and express the basic orientation of Buddhism: unguarded sensory contact gives rise to craving and clinging to impermanent states and things, which are dukkha, "unsatisfactory," "incapable of satisfying" and painful. This craving keeps us caught in saṃsāra, "wandering", usually interpreted as the endless cycle of repeated rebirth,refn|group=note|name="ego-rebirth|Buddhist modernism and some Theravadins have reinterpreted these teachings as "birth of ego".
