70.31

答。將所慮簡之。意云。夫為所緣緣者。須對能緣慮法。所慮。方名所緣緣。今鏡面既非能緣慮法者。即鏡中人影。及外邊人本質。亦不得名所慮法。既闕所慮義者。不成所緣緣。

Answer: One excludes this by using 'that which is deliberated upon.' The meaning is: to be an objective condition, it must be an object of deliberation in relation to a dharma that is capable of cognition and deliberation; only then is it named an objective condition. Now, since a mirror's surface is not a dharma capable of cognition and deliberation, the reflection of the person in the mirror and the external archetype of the person cannot be named dharmas that are deliberated upon either. Since they lack the meaning of being deliberated upon, they do not constitute objective conditions.
