大方廣佛華嚴經隨疏演義鈔 58.17

58.17

第三願，以八相如離世間者，今經具列，彼各有十。然亦有佛不具八者，如天王佛，白衣成道故；若以離俗為出家，則亦具矣。須扇多佛無生可化，則不具轉法輪；留一化佛半劫化人，是則亦具。然論釋一切處云「順眾生見」，故下料揀「何故不處色無色界？恐眾生云：此難處來，不為我成故。」二云「何故不處他化等而生兜率？令眾生知捨彼勝樂，為愍我故。」三「問：何故下生人中，捨於天樂？為愍我故。」四「何故處胎示現同生？增長力故。」五「問：何故自成正覺？示非餘佛教化，顯丈夫力成就，非因他得菩提故。」六「問：何故入涅槃？為令懈怠眾生懃心修道故。」此等略舉，示八相中一義而已。下離世間各具十義，故疏全指。

Regarding the third vow, taking the eight aspects as in the 'Transcending the World' chapter: the present sūtra lists them fully, and each has ten [aspects]. However, there are also Buddhas who do not possess all eight, such as King of Heaven Buddha, who attained the Way in white robes; if one regards leaving the mundane as going forth from household life, then he also possessed it. Susānta Buddha had no sentient beings to transform, so he did not possess the turning of the wheel of the Dharma; he left an emanated Buddha for half a kalpa to transform people, so in that sense he also possessed it. However, the treatise, explaining 'in all places', states: 'in accordance with the views of sentient beings'. Therefore, in the analysis below: 'Why does he not reside in the form or formless realms? For fear that sentient beings would say: "He came from this place of difficulty, he did not accomplish it for my sake."' Second, it states: 'Why does he not reside in Paranirmitavaśavartin and so forth, but is born in Tuṣita? To let sentient beings know that he renounced those superior pleasures out of pity for me.' Third, 'Question: Why is he born down among humans, renouncing heavenly pleasures? Out of pity for me.' Fourth, 'Why does he abide in the womb, manifesting birth like others? To increase power.' Fifth, 'Question: Why does he achieve true awakening by himself? To show that he was not taught and transformed by other Buddhas, to demonstrate accomplishment through the power of a hero, and that he did not attain bodhi dependent on others.' Sixth, 'Question: Why does he enter nirvāṇa? To cause indolent sentient beings to cultivate the Way with diligent minds.' These are cited briefly, showing merely one meaning among the eight aspects. Below in 'Transcending the World', each possesses ten meanings, which is why the commentary refers to it entirely.
