答：彼明三乘為三根，此中直取利鈍判三根。何以知然？文云「諸子之中有失心者」則是鈍根，「不失心者」即是利根。

Answer: There it explains the three vehicles as the three capacities, whereas here it directly takes sharpness and dullness to determine the three capacities. How do we know this to be so? The text says: 'Among the sons, those who had lost their minds' are the dull capacities, and 'those who had not lost their minds' are the sharp capacities.
