法華義疏 6.229

6.229

大意取解行人耳。有解則堪相對，悟有行則是道心，若聞實說則能如說修行也。

The general intention is simply to select people of understanding and practice. Having understanding, they are fit to face it; awakening with practice, there is the resolve for the Way; and hearing the real exposition, they will be able to cultivate practice in accord with what has been explained.
