Grammatical Analysis
Ādīnavañāṇa: [nt.] Knowledge of danger; knowledge of disadvantage. Formed by ādīnava (danger, fault, disadvantage) + ñāṇa (knowledge).
Orthodox Definition
Flowing directly from the knowledge of fearfulness, Ādīnavañāṇa is the realization that because all conditioned things are continuously collapsing, they are fundamentally dangerous, utterly devoid of satisfaction, and deeply flawed.
The meditator sees all of saṃsāra as a burning house. There is no longer any allure or deception in sensual pleasures, celestial rebirths, or deep meditative absorptions, because their inherent vulnerability is entirely exposed. Only the unconditioned state, Nibbāna—where there is no arising, passing, or formation—is seen as peaceful and secure.
