大方廣佛華嚴經疏 25.17

25.17

第七「恒以佛日」下明所行無礙，觀察如來生在世間不為世法所礙功德，顯示如來所化之中無高下礙，故次明之。謂世八風不能拘礙故。親光名降魔功德，謂色等境不能亂故。文中以佛身日普照法界則橫無礙，常現不沒則竪無礙。不以無信生盲等而不現故，正顯八風不礙。「恒住」已下顯無礙因，無有變異示無礙相，如摩尼珠不隨物變。不著我所於內無礙，世法不染於外無礙，由住出世如蓮華故。如有頌云「諸佛常游於世間，利樂一切有情類。八法勢風邪分別，不能傾動不拘礙。」

Seventh, from "constantly with the sun of the Buddha" onwards explains unimpeded conduct, contemplating the Tathāgata's virtue of being born in the world without being hindered by worldly dharmas, showing that among those transformed by the Tathāgata there is no obstruction of high or low; hence it is explained next. This means that the eight worldly winds cannot constrain or obstruct him. Śīlabhadra calls this the virtue of subjugating Māra, meaning that sensory realms such as form cannot disrupt him. In the text, that the sun of the Buddha's body universally illuminates the dharmadhātu is horizontal unimpededness; that it is constantly manifest and never sets is vertical unimpededness. Not failing to manifest on account of the faithless or those born blind directly reveals that the eight winds do not obstruct him. From "constantly abiding" onwards reveals the cause of unimpededness; having no change demonstrates the mark of unimpededness, just as a maṇi jewel does not change with external objects. Not clinging to 'what is mine' is unobstructed internally; being untainted by worldly dharmas is unobstructed externally, because he abides in transcendence like a lotus. As a verse says: "All Buddhas constantly roam the world, / benefiting and delighting all sentient beings. / The mighty winds of the eight dharmas and erroneous discriminations / cannot sway or constrain them."
