金光明經文句記 2.165

2.165

二、「如如」下，釋義。修行所感二種之報，乃是始覺與本覺合，即以始本而為境智，此二不異故名曰如。各二如者，智如如境、境如如智故也。復以菩提名如、如智為能應冥，法性名於如、如之境為所應冥。以函蓋合，先喻應義。函蓋雖合，猶存際畔，復以水乳喻其相冥，此乃泯然而成一相。始覺本覺義二體一，正同於此。

Second, from "Thusness..." onward: explaining the meaning. The two kinds of reward induced by cultivation are precisely the union of initial awakening with original awakening, where initial and original [awakening] are taken as object and wisdom; because these two are not different, they are named "Thusness." That each has two Thusnesses is because wisdom is such as the object of Thusness, and the object is such as the wisdom of Thusness. Furthermore, bodhi is named Thusness, with the wisdom of Thusness being that which can adapt and merge; and the dharma-nature is named the object of Thusness, being that which is adapted to and merged with. The fitting together of a box and its lid first illustrates the meaning of adaptation. Although the box and its lid fit together, their boundaries still remain; hence the mixture of water and milk further illustrates their mutual merging: this is merging to become a single characteristic. Initial awakening and original awakening are two in meaning but one in substance, exactly like this.
