Śūnyatā (/ʃuːnjəˈtɑː/ shoon-yə-TAH; Sanskrit: शून्यता; Pali: suññatā), translated most often as emptiness, vacuity, and sometimes voidness, or nothingness is an Indian philosophical concept। It is either an ontological feature of reality, a meditative state, or a phenomenological analysis of experience.
One example of this usage is in the Pheṇapiṇḍūpama Sutta (SN 22:95), which states that on close inspection, each of the five aggregates are seen as being void (rittaka), hollow (tucchaka), coreless (asāraka). In the text a series of contemplations is given for each aggregate: form is like a lump of foam (pheṇapiṇḍa); sensation like a water bubble (bubbuḷa); perception like a mirage (marici); formations like a plantain tree (kadalik-khandha); and cognition like a magical illusion (māyā).
