The Same Topic, Explained Three Different Ways

The Vibhanga, the Book of Analysis, takes eighteen major categories central to Buddhist doctrine, the five aggregates that constitute a person, the sense bases, the elements, the Four Noble Truths, the faculties, dependent origination, and the four foundations of mindfulness among them, and works through each one using three distinct analytical approaches in succession: first the suttanta method, presenting the topic largely as it appears in the discourses of the Sutta Pitaka, then the more technical abhidhamma method, applying the fuller categorizing apparatus developed in the Dhammasangani, and finally a catechism section posing and answering a rapid series of precise questions designed to test and sharpen a student's exact understanding of the category's boundaries. This threefold treatment gives the Vibhanga an unusually direct pedagogical value distinct from the other Abhidhamma books, since placing the more familiar sutta-style explanation directly alongside the more technical abhidhamma restatement allows a reader to see explicitly how the systematic Abhidhamma analysis relates back to, and claims to clarify rather than contradict, the earlier and more widely known teaching of the discourses. Its chapter on dependent origination is regarded by many scholars and practitioners as one of the clearest canonical treatments of that famously difficult twelve-link chain of conditioned arising anywhere in the Pali Canon.
