成唯識論述記 5.422

5.422

述曰：若起彼地藏識現行，除於種子，乃生彼地。為簡種子，故論說言「異熟藏識」。因中染污第七末那緣彼執我，繫屬第八名彼所繫。八非能繫，七非所繫，相從名繫，不可難以相應、所緣二縛名繫，相從相屬是此繫義。第八是所屬，第七為能屬，即是以彼所緣為所屬，第七屬彼也。如王為所屬，臣等為能屬，隨王繫國。

The Commentary states: If it gives rise to the actual manifestation of the storehouse consciousness of that bhūmi, excluding the seeds, it is then born in that bhūmi. To distinguish them from seeds, the treatise says "ripening storehouse consciousness." In the causal state, the defiled seventh manas takes that as object and grasps it as self; being bound to and subordinate to the eighth, it is called bound to that [bhūmi]. The eighth is not what binds, and the seventh is not what is bound; it is called "bound" by conformity. One must not object on the basis that bondage refers to the two bondages of association and intentional object; conformity and subordination constitute the meaning of bondage here. The eighth is that which is belonged to, and the seventh is that which belongs; that is, taking its intentional object as that which is belonged to, the seventh belongs to it. Just as the king is that which is belonged to and the ministers are those who belong, following the king they are bound to the state.
