7.8

此一下，二、釋體字。全作生滅即事法界，全作真如即理法界。既是一體所為，則令二無障礙，即是理事無礙法界也。二皆言作者，生滅即隨緣變作，真如即轉改其名曰作，二義俱無能所，義言作也。

[On] "This one..." below: second, explaining the word "essence" (體). Completely functioning as arising and ceasing, it is the dharmadhātu of phenomena; completely functioning as tathatā, it is the dharmadhātu of principle. Since both are wrought of one essence, they cause the two to be without obstruction, which is the dharmadhātu of the non-obstruction of principle and phenomena. The reason both are said to "function as" (作) is that arising and ceasing change and function according to conditions, while tathatā transforms and changes its name, which is called "functioning"; both meanings lack subject and object, and are conceptually spoken of as "functioning."
