Annitya
Impermanence (Pāli: अनिच्चा anicca; Sanskrit: अनित्य anitya; Tibetan: མི་རྟག་པ་ mi rtag pa; Chinese: 無常 wúcháng; Japanese: 無常 mujō; Korean: 무상 musang; Thai: อนิจจัง anitchang, from Pali "aniccaŋ") is one of the essential doctrines or three marks of existence in Buddhism. The term expresses the Buddhist notion that all of conditioned existence, without exception, is in a constant state of flux. The Pali word anicca literally means "inconstant", and arises from a synthesis of two separate words, 'Nicca' and the "privative particle" 'a'. Where the word 'Nicca' refers to the concept of continuity and permanence, 'Anicca' refers to its exact opposite; the absence of permanence and continuity.
