成唯識論述記 6.165

6.165

述曰：若在因中，或五俱起，或一一別生。若在果時，一向定有，此中即是諸位容有。若轉依、未轉依皆不遮故。

The Commentary states: If in the cause, sometimes the five arise together, and sometimes they arise individually. If in the fruition, they are definitely present without exception; here it is that they may be present in all states, because neither the transformed basis nor the untransformed basis is precluded.
