Overview
As a meditator engages in strict vipassanā (insight) meditation, their realization does not happen all at once. According to the Mahāvihāra tradition, the mind passes through a highly predictable, standardized sequence of sixteen distinct experiential knowledges (ñāṇa), charting the exact psychological journey from mundane observation to the supramundane realization of Nibbāna.
The List
- Nāmarūpapariccheda-ñāṇa: Knowledge defining mentality-materiality.
- Paccayapariggaha-ñāṇa: Knowledge discerning the conditions/causes of mentality-materiality.
- Sammasana-ñāṇa: Knowledge of comprehending the three characteristics (impermanence, suffering, non-self).
- Udayabbaya-ñāṇa: Knowledge of arising and passing away (the crucial turning point of insight).
- Bhaṅga-ñāṇa: Knowledge of dissolution (seeing only the vanishing of phenomena).
- Bhaya-ñāṇa: Knowledge of terror/fear (seeing the dissolving aggregates as dangerous).
- Ādīnava-ñāṇa: Knowledge of danger/disadvantage.
- Nibbidā-ñāṇa: Knowledge of revulsion/disenchantment toward all formations.
- Muñcitukamyatā-ñāṇa: Knowledge of the desire for deliverance.
- Paṭisaṅkhā-ñāṇa: Knowledge of reflective contemplation (re-evaluating the 3 characteristics to escape).
- Saṅkhārupekkhā-ñāṇa: Knowledge of equanimity toward all formations (perfect, fearless neutrality).
- Anuloma-ñāṇa: Conformity knowledge (the mind aligns completely with truth).
- Gotrabhū-ñāṇa: Change-of-lineage knowledge (the mind leaves the worldly lineage and strikes Nibbāna for the first time).
- Magga-ñāṇa: Path knowledge (the supramundane flash that destroys fetters).
- Phala-ñāṇa: Fruition knowledge (the peaceful result of the path).
- Paccavekkhaṇa-ñāṇa: Reviewing knowledge (the subsequent intellectual review of what was just attained and the defilements abandoned).
