法華文句記 3.76

3.76

因光見處一切皆妙，當知光是殊妙之本，況復諸瑞並中為本，光即中也。他六皆中由光亦爾。

Where seen due to the light, everything is wondrous; one should know that the light is the fundamental source of the extraordinary and wondrous. Moreover, all the portents alike take the middle as fundamental, and the light is precisely the middle. The other six are all the middle, and due to the light it is also thus.
