花嚴經文義綱目 1.43

1.43

初定佛身者，問：此八會佛是何等身：答：有人釋云是化身佛，以菩提樹下八相成道，是化身故；不離昇天，是重化故；以釋迦異名名盧舍那，非別報身故。又有釋云說此經佛是實報身，以是盧舍那法界身故，居蓮華藏淨土中故。下第七會初歎佛有彼二十一種殊勝功德，是實報也；但以不離化故，該此樹下，非是化身。今釋此佛，準下文中是十佛之身，通三世間，以說十信及三賢等地前所見非實報故。然居花藏非是化故，國土身等非前二故，具攝前二，性融通故。具足主伴如帝網故，是唯周遍法界十佛之身。

First, on determining the Buddha's body: Question: What kind of body is the Buddha of these eight assemblies? Answer: Some explain that it is an emanation body (nirmāṇakāya) Buddha, because attaining awakening through the eight aspects beneath the bodhi tree is the emanation body; ascending to heaven without leaving is a further emanation; and Śākya is an alternative name for Rocana, not a separate reward body (saṃbhogakāya). Others explain that the Buddha expounding this sūtra is the true reward body, because it is Rocana's dharmadhātu body and resides in the Padmagarbha pure land. Below, at the beginning of the seventh assembly, praising the Buddha as having those twenty-one kinds of superlative virtues refers to the true reward [body]; it is merely that because it does not depart from emanation, it extends to beneath this tree, and is not an emanation body. Now, explaining this Buddha based on the text below: it is the body of the ten Buddhas, pervading the three realms, because what is seen prior to the stages—when expounding the ten faiths, the three stages of the worthy, and so forth—is not the true reward [body]. However, residing in the Padmagarbha [world] is not an emanation, and the body of the land and so forth are not the previous two [bodies alone], for it fully subsumes the previous two, their natures being harmoniously integrated. It completely possesses host and retinue like Indrajāla; hence, it is solely the body of the ten Buddhas that completely pervades the dharmadhātu.
