首楞嚴義疏注經 6.23

6.23

第十地菩薩坐華王座，垂成正覺，亦須別佛說教聞熏，令斷最後微細無明。故觀世音現第十重他受用身而為說法。言勝解者，於決定境忍可印持，不為異緣之所引轉，此指最極根本無分別智將圓滿時，故名勝解。然此菩薩登住已去，雖為因位，便能現上位身為彼說法，以此圓證一位即諸位，更無淺深，故能現耳。

A bodhisattva of the tenth stage sits on the flower-king throne, on the verge of achieving correct enlightenment; they still require another Buddha to expound the teaching for them to hear and be perfumed by, enabling them to sever the final subtle ignorance. Therefore, Avalokiteśvara manifests the tenth-tier other-enjoyment body to expound the Dharma for them. 'Supreme resolve' (adhimukti) refers to giving assent and seal of certainty regarding a determined realm, not being diverted by other conditions; this refers to the moment when the utmost fundamental non-conceptual wisdom is about to become complete, hence called 'supreme resolve.' Yet once this bodhisattva ascends to the abodes, although in the causal stage, they can already manifest bodies of higher stages to expound the Dharma for them; because of this perfect realization, one stage is all stages without shallowness or depth, and hence they can manifest them.
