4.31

下句下，二、釋相大。即無量功德藏一句，釋上標中相之一字。法身者約果，如來藏者據因，以體不二，故雙舉也。藏約含攝，身名積聚，所攝所積皆性功德。如下文云：二者相大，謂如來藏具足無量性功德故。所謂自體有大智慧光明義，遍照法界義，真實識知義。乃至云：無有所少義，故名為如來藏，亦名如來法身。

"The lower line…" introduces the second part, explaining the greatness of attributes. That is, the single line "storehouse of immeasurable merits" explains the single word "attributes" (相) in the designation above. "Dharmakāya" is spoken in terms of the fruit; "tathāgatagarbha" is based on the cause. Because their essence is non-dual, both are mentioned together. "Storehouse" (藏) refers to containing and embracing; "body" (身, kāya) is named for accumulation. What is embraced and what is accumulated are both intrinsic merits of the nature. As the text below states: "Second is the greatness of attributes, meaning that the tathāgatagarbha is replete with immeasurable intrinsic merits of the nature." That is, its self-essence has the meaning of great wisdom and luminosity, the meaning of illuminating the entire dharmadhātu, the meaning of true knowing, and so on, down to: "the meaning of lacking nothing; therefore it is called the tathāgatagarbha, and is also called the tathāgata's dharmakāya."
