唯識二十論述記 1.233

1.233

述曰：解上三句頌。觀宜密說，非別實有色等十處。機宜如何？所化眾生執有實我，為破彼我執，說有色等十，令除一實見。故舊論頌云：「色等入有教，為化執我人」，即此頌云依所化機宜，說色等也。

The commentary says: This explains the first three lines of the verse. Observing their aptness, he spoke intentionally; the ten bases such as form are not distinct and substantially real. How is it according to their aptness? The sentient beings to be transformed grasped a substantially real self; in order to shatter their grasp of a self, he spoke of the ten [bases] such as form to cause them to eliminate the view of a single real entity. Thus the verse in the older translation says: 'The teaching on the existence of the entrances (āyatana) such as form was to guide those who grasp at a person,' which is just what this verse means by saying that he spoke of form and so forth based on the aptness of those to be guided.
