受望愛為三緣者，由現行受同時起愛為俱有緣等，愛望取為俱。有云：由貪俱行故於隨順取法中欲樂安立者，愛與能取實不同時，所取所為取之因緣與愛俱有，愛望取成俱有緣，取望有為三緣。

Regarding feeling serving as three conditions for craving: active feeling simultaneously giving rise to craving is the coexistent condition, and so forth. Craving is coexistent with respect to grasping. There is an explanation saying: In the passage, "Because of co-functioning with greed, desire and pleasure are established among phenomena that conform to grasping," craving and the active grasper are actually not simultaneous, but the grasped object and the cause and condition for performing grasping coexist with craving; craving becomes a coexistent condition for grasping, and grasping serves as three conditions for existence.
