金光明經文句記 4.209

4.209

四、「與此」下，與經體相應。佛示二空顯法性體，不照三諦豈稱法性無量甚深？故知今解與性相應。此性名為金剛寶藏，若偏照之，德非具足。

Fourth, from "With this..." onward, corresponding with the substance of the sūtra. The Buddha reveals the two emptinesses to disclose the substance of dharma-nature; if one does not illuminate the three truths, how could it be called the immeasurable, profound dharma-nature? Thus we know the present understanding accords with the nature. This nature is called the adamantine treasury; if one illuminates it onesidedly, its virtues are not complete.
