Vipassanā-ñāṇa
The Vipassanā-ñāṇas (Pali, Sinhala: Vidarshana-jñāna) or insight knowledges are various stages that a practitioner of Buddhist Vipassanā ("insight", "clear-seeing") meditation is said to pass through on the way to nibbana. This "progress of insight" (Visuddhiñana-katha) is outlined in various traditional Theravada Buddhist commentary texts such as the Patisambhidamagga, the Vimuttimagga and the Visuddhimagga.
