13.14

This Abhidharmapiṭaka differs across the various schools. Those that have circulated in this land are the most numerous compared to others. Now, on the basis of the Sarvāstivāda root texts, the body śāstra is placed first, the foot śāstras follow next, and branches such as the vibhāṣās are arranged at the end. Since the other schools are numerous and difficult to categorize by rules, we await the future [for their ordering]; here they have no fixed precedence.
