大方廣佛華嚴經隨疏演義鈔 3.24

3.24

Regarding [the passage in] the Commentary beginning with "There is nothing that does not flow forth from this dharmadhātu": this is the second part, substantiating both of the above; first citing the Mahāyānasaṃgraha and then the Lotus Sūtra. The first citation, from the Mahāyānasaṃgraha—'There is nothing that does not flow forth from the dharmadhātu'—substantiates its being the root that unfolds the gradual teachings. 'Because there is nothing that does not return to this dharmadhātu' substantiates its being the root that gathers in the branches. This is using meaning to verify the teaching. It means that what the treatise clarifies—the reward and transformation bodies and so forth—all arise from the dharmakāya and return to the dharmakāya. The dharmakāya and the rest are the meaning; now, by analogizing the dharmakāya to the Avataṃsaka, it is called using meaning to verify the teaching.
