仁王經疏 3.286

3.286

釋曰：自下第七法師。文別有三：初標位列名、次顯地別行、後行位時分。此即初也。言爾炎者，此云智母。謂此位中，生法二空能生聖道，故名智母。言聖覺達者，即所生聖智。前之三地，行施戒修相同凡夫，於此位中起道品觀，初證聖覺、達二空理，名聖覺達。

Explanation: From here below is the seventh Dharma master. The text has three parts: first, marking the rank and setting forth the name; next, showing the distinct practice of the bhūmi; and finally, the temporal stage of the rank of practice. This is the first. 'Jñeyam' (爾炎) is translated here as 'mother of wisdom'. It means that within this rank, the twofold emptiness of persons and dharmas is able to give birth to the noble path, hence it is named 'mother of wisdom'. 'Sage-awakened and thoroughly penetrating' refers to the noble wisdom that is born. In the preceding three bhūmis, the practice of giving, discipline, and cultivation is similar to that of ordinary persons; in this rank, one gives rise to the contemplation of the limbs of the path, first realizing noble awakening and thoroughly penetrating the principle of the twofold emptiness, hence it is named 'sage-awakened and thoroughly penetrating'.
