The Abhidharma-mahavibhasa-Sastra is written as bible by scholars of Sarvastitva-vadin. This article is keeping an eye on their expressions of the technical term Yan-Li(厭離) in the book to see how it is different from the original canons -- Agmas and Nikayas. We can see the writers gave Yan-Li(厭離) some special meanings. They also placed Yan-Li(厭離) at a specific position on their own path to purification.
