Grammatical Analysis
Anuppādāñāṇa: [nt.] knowledge of non-arising; knowledge of non-origination. Formed by negative prefix an (not) + uppāda (arising, birth, generation) + ñāṇa (knowledge).
Orthodox Definition
Anuppādāñāṇa is the inseparable twin to Khayāñāṇa (knowledge of destruction). While Khayāñāṇa is the realization that all existing defilements have been successfully killed, Anuppādāñāṇa is the absolute, verified knowledge that those defilements can never arise again in the future, and therefore, no future rebirth (jāti) can ever be generated.
The commentaries use the simile of a tree struck by lightning. Khayāñāṇa is seeing the tree burn to ash; Anuppādāñāṇa is knowing that the ashes can never sprout into a tree again.
Together, these two knowledges (khaye ñāṇaṃ and anuppāde ñāṇaṃ) constitute the absolute pinnacle of Buddhist epistemology, forming the complete “Knowledge of Enlightenment” (Bodhi-ñāṇa) that guarantees the Arahat is permanently immune to the physics of saṃsāra.
