成唯識論演祕 2.439

2.439

釋曰：二十二根中是何根分。論主答云：此無所屬，先業所引時量決定而建立故，唯說假有。

Explication: Among the twenty-two faculties, which faculty's portion is it? The author of the treatise answers: "This has no belonging, because it is established on the basis of a determined duration projected by prior karma; it is said to exist only nominally."
