shunya (shoon - yuh): Sanskrit - zero point.

In Buddhist philosophy, the voidness that constitutes ultimate reality; sunyata is seen not as a negation of existence but rather as the undifferentiation out of which all apparent entities, distinctions and dualities arise. Although the concept is encountered occasionally in early Pali texts, it's full implications were developed by the 2nd-century Indian philosopher Nagarjuna. The school of philosophy founded by him, the Madhyamkia (Middle Way), is sometimes called the Sunyavada, or Doctrine That All Is Void.
