4.26

以用下，二、通伏難，初正通也。難曰：「既云彼身體相合配屬佛，其義則順，何以却云法寶耶？」故此釋之，以佛有三身，用大之中已攝報、化，即屬佛寶；體、相二大正是法身，配歸法寶。於理甚宜。

From "using function" downward, second, resolving an implicit objection, first directly resolving it. The objection says: "Since it says 'the essence and attributes of that body,' it should match and belong to the Buddha, and its meaning would be smooth; why instead does it say 'the Dharma Jewel'?" Hence this is explained: because the Buddha has three bodies, and the greatness of function already subsumes the sambhogakāya and nirmāṇakāya, it belongs to the Buddha Jewel; the two greatnesses of essence and attributes are precisely the dharmakāya, and matching them to the Dharma Jewel is completely fitting in principle.
