Grammatical Analysis
Parinibbāna: [nt.] Final Nibbāna; complete blowing out; final passing away. Formed by intensive prefix pari (complete, total) + nibbāna (extinguishment).
Orthodox Definition
Doctrinally, Theravāda distinguishes between two phases of Nibbāna.
- Sa-upādisesa-nibbāna (Nibbāna with residue remaining): This occurs when a practitioner attains Arahatship during their life. The defilements are completely destroyed, but the physical body and mental faculties (the five aggregates) continue to operate until their karmic lifespan is exhausted.
- Anupādisesa-nibbāna (Nibbāna with no residue remaining): This is Parinibbāna. It occurs at the exact moment of biological death of an Arahat or a Buddha.
At Parinibbāna, the final mind-moment (cuti-citta) ceases without generating a rebirth-linking consciousness (paṭisandhi). The aggregates break apart and are never formed again. It is the absolute, final, and total cessation of the cycle of saṃsāra. The Buddha stressed that asking “where” an Arahat goes after Parinibbāna is an invalid question, akin to asking where the flame goes when the fuel is exhausted.
