仁王護國般若波羅蜜多經疏 3.87

3.87

解曰：諸王眾中者，如前應悉。就命時到者，舉所怖事，令發心故。從此第三轉教般若。

Explanation: "Amidst the assembly of kings": as before, one should understand it. "The time to face death has arrived": he brought up what was feared in order to make them generate the mind [of awakening]. From here, the third part concerns passing on the teaching of prajñā.
