3.195

由希望生故，於追求時，能發隨眠等者，由愛希求勝境和合惡境別離，而熏種子發取隨眠，及引隨順生取之法，故取得生，是故偏說愛緣於取。

Regarding "Because hope arises, at the time of pursuing, it can activate latencies," and so forth: through craving, desiring conjunction with superior objects and separation from bad objects, it perfumes seeds and activates the latencies of grasping, and induces dharmas that conform to generating grasping; thus grasping comes to arise. For this reason, craving is singled out as conditioning grasping.
