妙法蓮華經玄贊 2.278

2.278

贊曰：第六同答成。有四：一傳燈眷屬，二因說此經，三時節短長，四大眾安樂。此初也。

The commentary states: The sixth is the accomplishment of matching answers. It has four parts: first, transmitting the lamp to the retinue; second, the cause for preaching this sūtra; third, the brevity or length of the duration of time; fourth, the peace and joy of the great assembly. This is the first.
