上來廣辨六種善巧中已說四訖。自下第五辨處非處善巧。文中有四：初結前生後；二、開列四門；三、依門辨釋；四、指餘不現。

Above, within the extensive analysis of the six kinds of skill, four have already been explained. From here on, the fifth analyzes skill in possibilities and impossibilities. Within the text there are four parts: first, concluding the preceding and introducing what follows; second, opening and listing the four approaches; third, analyzing and explaining according to the approaches; fourth, indicating what remains unexpressed.
