俱舍論疏 2.138

2.138

論「何等為八至諸無漏見」，釋八見名體也。如文可解。《婆沙》四十九云「以四事故名見：一徹視故、二推度故、三堅執故、四深入故。」

The *Śāstra* states: "What are the eight?... all undefiled views." This explains the names and essences of the eight views. It can be understood according to the text. Fascicle 49 of the *Vibhāṣā* says: "They are called 'views' because of four factors: 1. Piercing observation; 2. Deliberation; 3. Firm adherence; 4. Deep entry."
