2.88

釋曰：隨根變者，識隨根變。根若轉變，識亦異故。謂根若益，其識即明；根若有損，識便昧故。非境有變令識有異，以識隨根，不隨境故。依名唯在眼等非餘。言眼等者，眼等六界也。

The explanation says: 'In accordance with the modification of the faculty' means that consciousness alters in accordance with the faculty. If the faculty changes, consciousness is also different; that is, if the faculty is benefited, its consciousness becomes clear, whereas if the faculty is impaired, the consciousness becomes dim. It is not that a change in the object causes consciousness to be different, because consciousness follows the faculty and does not follow the object. The designation of 'basis' resides only in the eye and the others, and not in anything else. 'The eye and the others' refers to the six elements of the eye and the rest.
