One who has learned much, and who retains and accumulates what he has learned. Those teachings that are good in the beginning, good in the middle, and good in the end, that have a true goal and are well articulated, and that set out the perfectly complete and pure spiritual life—he has learned many such teachings, retained them in mind, recited them verbally, mentally investigated them, and penetrated them well by view. One who has properly learned both Monastic Codes in detail; who has analyzed them well, thoroughly mastered them, and investigated them well, both in terms of the rules and their detailed exposition. One who is firmly committed to the Monastic Law. One who is capable of making both sides relax, of persuading them, of convincing them, of making them see, of reconciling them. One who is knowledgeable about the arising and resolution of legal issues. One who understands legal issues. One who understands the arising of legal issues. One who understands the ending of legal issues. One who understands the way to the ending of legal issues. And he should be appointed like this.
