金剛般若波羅蜜經註解 1.210

1.210

Above it was said that the substance of tathatā realized by the Tathāgata pervades all places, and can indeed be called tall and large. Fearing again that Subhūti would give rise to a view of being tall and large, the Buddha again set forth a metaphor to question him, saying: "It is just like a person's body being tall and large." Subhūti had an awakening based on the metaphor, and immediately said: "It is not a large body; it is named a large body." The treatise says: "'Large body' has two meanings: first, pervading all places is the dharmakāya; second, greatness of merit is the saṃbhogakāya. Both of these two bodies are free from all marks; therefore they are called 'not.'"
