大般涅槃經集解 8.34

8.34

案僧宗曰：向問般若，此問法身。上明無盡，此明不壞。如世金剛，體不可壞、能壞萬物。取譬法身，三相不能移其神、萬化莫能變其體也。寶亮曰：體相身命，實乃不殊；就義而辨，不得無異。身當法體，命語始終，故分為二問也。智秀曰：此第三問法身果也。

Sengzong states: The previous asked about prajñā; this asks about the dharmakāya. The above clarified inexhaustibility; this clarifies indestructibility. Like worldly diamond (vajra), its substance cannot be destroyed, yet it can destroy all things. Drawing the analogy to the dharmakāya: the three marks cannot alter its spirit, and the myriad transformations cannot change its substance. Baoliang states: The substance, marks, body, and lifespan are in truth not different; yet discerning them according to meaning, they cannot lack distinction. The body corresponds to the substance of the Dharma, while life speaks of beginning and end; hence they are divided into two questions. Zhixiu states: This is the third question, on the fruition of the dharmakāya.
