2.242

一所棲同處、二居戒甚勉、三禪定隱跡、四禪外講學、五相敬相和，略張四行，六和備矣。

First, their dwelling is in the same place; second, they dwell in the precepts very diligently; third, they conceal their traces in dhyāna meditation; fourth, outside of dhyāna they lecture and study; fifth, they respect each other and harmonize with each other. These briefly spread out four practices, and the six harmonies are complete.
