成唯識論述記 6.320

6.320

述曰：自下第三解。資糧、加行、見、修、無學五位，如《對法》第八末、第九等解。問：既通三乘，三乘無學云何無足，不捨善軛，果已滿故？

The Commentary states: Below is the third explanation: the five stages of equipment, preparation, seeing, cultivation, and no-more-learning, as explained at the end of fascicle eight and fascicle nine of the Abhidharma-samuccaya. Question: Since it applies to the three vehicles, how can the no-more-learning stage of the three vehicles be 'without complacency' and 'not casting off the wholesome yoke,' when their fruit has already been fulfilled?
