Some Theravada Buddhists also follow the presentation of the path laid out in Buddhaghosa's Visuddhimagga. This presentation is known as the "Seven Purifications" ("satta-visuddhi"). This schema and its accompanying outline of "insight knowledges" ("vipassanā-ñāṇa") is used by modern influential Theravadin scholars, such Mahasi Sayadaw (in his "The Progress of Insight") and Nyanatiloka Thera (in "The Buddha's Path to Deliverance").
