Vipassanā

Vipassanā or vipaśyanā (विपश्यना, Sanskrit, Chn. 觀 guān;Tib. ལྷག་མཐོང་, lhaktong; Wyl. lhag mthong) in the Buddhist tradition means insight into the true nature of reality. In the Theravadin context, this entails insight into the three marks of existence, the impermanence and unsatisfactoriness of every conditioned thing that exists and non-self.
