1.78

阿羅漢功德成就者，彼十六句示現三種門攝義應知。何等三種門？一者上上起門、二者總別相門、三者攝取事門。

"As for the fulfillment of virtues of an arhat, one should know that those sixteen phrases demonstrate three doors of subsumed meanings. What are the three doors? The first is the door of progressively higher arising; the second is the door of general and specific characteristics; the third is the door of grasping matters."
