2.81

論。答曰至能現於色　述曰。下答有二。先釋法身能現。後釋所現之色。前中亦二。先總舉。後別成。此初也。謂此法身即是報化色家之體。故能現色。若非色體。不名法身。色德名法。自體名身。是故法身名為色體。

[Treatise:] Answer: ... can manifest form.
[Exposition:] In the answer below there are two: first, explaining that the dharmakāya can manifest [form]; next, explaining the form that is manifested. In the first there are also two: first, a general statement; next, specific establishment. This is the first. This dharmakāya is precisely the essence of the domain of enjoyment and transformation forms; hence it can manifest form. If it were not the essence of form, it would not be called the dharmakāya. The virtues of form are called dharma, and the self-essence is called kāya (body); therefore, the dharmakāya is called the essence of form.
