妙法蓮華經玄贊 8.374

8.374

贊曰：下若依我軌儀佛便隨順。有三：一令聽，二得見，三令不忘念。此初。有三：一令化人集眾，二化四眾令聽，三令八部往聽。

The Eulogy states: Below is: if one complies with my rules, the Buddha will then facilitate it. There are three: first, causing them to listen; second, being able to see; third, causing them not to forget. This is the first. There are three [parts]: first, causing conjured persons to assemble the multitude; second, conjuring the four assemblies to listen; third, causing the eight classes to go and listen.
