瑜伽論記 16.198

16.198

有釋：此中生有與本有為依處，本有與死有為依處，死有與中有為依處，以前時有即中有故，五受根中喜樂捨可意境愛等所依，苦憂於不可意境等所依，捨通二種。

Some explain: "Here, rebirth-existence serves as the basis for fundamental existence, fundamental existence serves as the basis for death-existence, and death-existence serves as the basis for intermediate existence, because prior-time existence is just intermediate existence." Among the five feeling faculties, joy, pleasure, and equanimity are the bases for attachment toward agreeable objects and so forth; suffering and grief are the bases for disagreeable objects and so forth; equanimity connects to both.
