These four things lead to the continuation, persistence, and enduring of the true teaching. What four? Firstly, the mendicants memorize discourses that have been learned correctly, with well placed words and phrases. When the words and phrases are well placed, the meaning is interpreted correctly. This is the first thing that leads to the continuation, persistence, and enduring of the true teaching.

Furthermore, the mendicants are easy to admonish, having qualities that make them easy to admonish. They’re patient, and take instruction respectfully. This is the second thing that leads to the continuation, persistence, and enduring of the true teaching.

Furthermore, the mendicants who are very learned—inheritors of the heritage, who have memorized the teachings, the monastic law, and the outlines—carefully make others recite the discourses. When they pass away, the discourses aren’t cut off at the root, and they have someone to preserve them. This is the third thing that leads to the continuation, persistence, and enduring of the true teaching.

Furthermore, the senior mendicants are not indulgent or slack, nor are they backsliders; instead, they take the lead in seclusion, rousing energy for attaining the unattained, achieving the unachieved, and realizing the unrealized. Those who come after them follow their example. They too aren’t indulgent or slack … This is the fourth thing that leads to the continuation, persistence, and enduring of the true teaching. These are four things that lead to the continuation, persistence, and enduring of the true teaching.”
