有義：明了心中求無想果故，微微心所熏成種為果熟，因能招異熟，微微心中行想微劣，非別能求當異熟故。

Another opinion says: Because one seeks the fruit of non-conception during a lucid mind, the seeds perfumed by the extremely subtle mind become the maturation of the fruit. The cause can summon the maturation because in the extremely subtle mind the activity of conceptualization is weak and subtle, and it cannot separately seek the future maturation.
