仁王護國般若波羅蜜多經疏 3.330

3.330

The commentary explains: "In sovereign dual benefit" means that real cognition benefits oneself and skill-in-means benefits the ground, functioning with sovereignty in these two benefits. "Like water and waves" uses a simile to explain and establish it. Water symbolizes the fundamental cognition, and waves symbolize the subsequent cognition; the functions of these two are like waves and water. "Neither one nor different": because movement and stillness differ, they are not one; because apart from water there are no waves, they are not different; this is the meaning of the two cognitions being neither one nor different. "The pāramitās arisen from cognition are also neither one nor different": practices are aroused relying on cognition, and practices are concomitant with cognition; just like water and waves, they are also neither one nor different. Hereafter, the third part explains cultivating cognition and vows. This is divided into two: first, explaining the practices cultivated.
