請觀音經疏闡義鈔 1.105

1.105

「他人」下，問答。合在釋別名後，而在此者，或隨便、或文誤。問意者：設云菩薩三業俱觀機者，意輪鑑機，此義可了。身口是色，云何鑑機？故云「身口若為觀」。

Below "others," there is a question and answer. It ought to follow the explanation of the specific name, but being located here, it was either placed for convenience or is a textual error. The intent of the question is: supposing it is said that all three karmic actions of the bodhisattva contemplate capacity, that the mental wheel discerns capacity can be understood. Body and mouth are material; how can they discern capacity? Therefore it says: "How could body and mouth contemplate?"
