維摩經玄疏 5.138

5.138

四、類通三種般若者：一，實相般若；二，觀照般若；三，方便般若。真性解脫，即是實相般若；實慧解脫，即觀照般若；方便解脫，即方便般若。義推可解。

Fourth, analogously correlating the three kinds of prajñā: first, the prajñā of the true mark; second, the prajñā of contemplative illumination; third, the prajñā of expedient means. The liberation of the true nature is the prajñā of the true mark; the liberation of real wisdom is the prajñā of contemplative illumination; the liberation of expedient means is the prajñā of expedient means. The meaning can be understood by inference.
