仁王護國般若波羅蜜多經疏 2.609

2.609

解曰：言三乘者，三乘之人。言般若者，實相等也。不生不滅者，明體常也。自性常住者，謂彼實相體不生滅，不變易也。雖三乘者證解不同，論其智體等無異矣。從此第三總明覺性。

Explanation: "The three vehicles" refers to persons of the three vehicles. "Prajñā" refers to the true mark and so forth. "Unarisen and unceasing" explains that its substance is eternal. "Its intrinsic nature eternally abiding" means that the substance of that true mark does not arise or cease, and does not alter. Although the realization and understanding of the persons of the three vehicles differ, when discussing the substance of cognition, it is equal and without difference. Next, the third section generally explains the nature of enlightenment.
