妙法蓮華經玄義 6.19

6.19

至論諸法非去來今，非應非不應而能有應；亦可言法應，亦可言應應。法應則冥益，應應則顯益。分別冥顯有四義。如後說（云云）。

In the ultimate discussion, all dharmas are neither past, future, nor present; they are neither response nor non-response, yet they are able to have response. One may also speak of a dharma-response, and one may also speak of a response-response. The dharma-response is hidden benefit, while the response-response is manifest benefit. The differentiation of hidden and manifest has four meanings, as will be explained later (and so on).
