大方廣佛華嚴經疏 7.6

7.6

Third, the assembly of dragon kings. Following the verses and the Sanskrit text, there are eleven; the prose omits the fifth, having only ten dharmas.
The first is the dharma-gate of the Heavenly King of the west, and the second, as in the verses, will be explained below.
The third, together with the verse text, shares six meanings: 1. the realms of rebirth are the locus of transformation; 2. the pure sound is the instrument of transformation; 3. the Buddha's name is the dharma of transformation; 4. supernormal powers are the basis of transformation; 5. sentient beings are the capacity for transformation; 6. according with desires is the intent of transformation.
Fourth, 'universally manifesting...', etc.: a single pore universally manifests limitless environments and beings, because a pore, in accord with reality, can broadly contain; broadly containing is precisely being all-pervading. The Buddha who can manifest still abides within the pore; within the displayed lands, the manifestor and the manifested are not conflated; environment and being are distinct, and great and small remain clearly distinct: this is termed 'establishing distinctions'.
Fifth, Jingfa states: 'According to the Sanskrit text, there is the dragon king Jvālāna (Flame), who obtained the liberation gate of the Tathāgata's compassionate pity extinguishing all sentient beings' hindrances and entanglements of anger and delusion.' This means that when great compassion resides in the heart, the three poisons are all extinguished.
Sixth, 'disclosing...', etc.: the Buddha's great compassion is an ocean of merits, obtained only after the two provisions are completed. The compassion and merits of sentient beings are the hundred rivers; their manifestation in a single pore of the Buddha illustrates their shared essence. Once knowing they share the same essence, they naturally pay homage; because of being shown and enlightened to this, they attain great joy and bliss.
Seventh: compassionate sound coupled with wisdom is called pure; pure and free of craving, what fear or sorrow could there be?
Eighth, 'manifesting...', etc.: manifesting bodies and lands within the body.
Ninth: contemplating the Buddha's past practices as deep and vast, one therefore delights and rejoices. The word 'ocean' applies to both rejoicing and making offerings.
Tenth, 'manifesting...', etc.: performing sounds for the assembly, hence it says 'manifesting'. The sound has four meanings: 1. multiple types, meaning 'all'; 2. universal, meaning 'equal'; 3. fitting the faculties with elegance, hence 'delightful'; 4. a single sound according with every kind, hence 'unobstructed'; unobstructed is precisely expedient means.
Eleventh: this Anavatapta dragon dwells in a cool pool, producing fragrant and delicious water that flows into the four seas and directs the hundred rivers, timely spreading clouds of compassion and raining down sweet dew; therefore, it can extinguish all worldly sufferings.
