Grammatical Analysis
Suññatā: [f.] Emptiness; voidness. Derived from suñña (empty, void) + tā (abstract noun suffix, -ness).
Orthodox Definition
In orthodox Theravāda, Suññatā is not an absolute cosmic void or a mystical monistic essence. It has two highly specific applications:
- Conditioned Emptiness: Refers to the characteristic of non-self (anattā-lakkhaṇa). The five aggregates are “empty” (suñña) of a self, a soul, a resident entity, or anything belonging to a self.
- The Door to Liberation: When a meditator achieves Path knowledge (maggañāṇa) specifically through the intense contemplation of non-self (anattā), the realization of Nibbāna is classified as the “Emptiness Liberation” (suññatā-vimokkha).
Furthermore, Nibbāna itself is termed suññatā because it is utterly empty of all greed, hatred, delusion, and conditioned formations.
