瑜伽師地論略纂 3.19

3.19

「本法與顯，為異不異」等者，本法即果，先來有故。顯謂顯了，遇緣顯故。若不異者，法應常顯，本來果法先常有故，先顯今顯，不應道理。量云：汝宗果法先來應顯，即本法故，猶如本法。汝宗果法應今始有，以即顯故，如今始顯。本法比量，翻此可知。

Regarding "Is the fundamental phenomenon different or not different from its manifestation?" and so forth: the fundamental phenomenon is the effect, because it has existed from the beginning. Manifestation means being made manifest, because it becomes manifest upon encountering conditions. If they are not different, the phenomenon should always be manifest, because the primordial phenomenon of the effect has always existed before; that it was manifest before and is manifest now does not stand to reason. The formal inference is: "The phenomenon of the effect in your school should have been manifest from the beginning; because it is identical with the fundamental phenomenon; just like the fundamental phenomenon." "The phenomenon of the effect in your school should only now begin to exist; because it is identical with the manifestation; just like the manifestation that only now begins." The formal inference concerning the fundamental phenomenon can be understood by reversing this.
