瑜伽師地論略纂 4.150

4.150

二十五、三界繫中，欲界一切，上界一分等者，彼云：雖皆通三界，而有分有全。欲界有二性，無明、行、愛、取三性，有一業七果。上唯一性，無明、行、愛、取二性，有一業七果，故言一分。

25. Regarding "Bound to the three realms: all of the desire realm, a portion of the higher realms," and so forth: that [text] says: although all extend to the three realms, there are partial and complete. The desire realm has two natures: ignorance, formations, craving, and grasping have three natures; there is one karma and seven fruits. The higher [realms] have only one nature: ignorance, formations, craving, and grasping have two natures; there is one karma and seven fruits; therefore it is said to be 'a portion'.
