Śūnyatā (/ʃuːnjəˈtɑː/ shoon-yə-TAH; Sanskrit: शून्यता; Pali: suññatā), translated most often as "emptiness",[1] "vacuity", and sometimes "voidness",[2] or "nothingness"[3] is an Indian philosophical concept. Within Hinduism, Jainism, Buddhism, and other philosophical strands, the concept has multiple meanings depending on its doctrinal context. It is either an ontological feature of reality, a meditative state, or a phenomenological analysis of experience.
