注大乘入楞伽經 10.35

10.35

然修觀行者，須達能斷無性、所斷本空，無斷之斷方為正斷。若執定有者，則墮於常，不可斷故；若執定無，即墮於斷，失聖智故。故先德云：「佛本是而勤修，惑元無而須斷。」

However, those who cultivate the practice of contemplation must realize that that which is able to sever has no self-nature, and that which is severed is fundamentally empty; a severing without severing is genuine severing. If one grasps them as definitely existent, one falls into eternalism, because they could not be severed; if one grasps them as definitely non-existent, one falls into annihilationism, forfeiting holy wisdom. Therefore, the ancient virtuous ones said: 'The Buddha is fundamentally existent, yet one diligently cultivates; delusion is fundamentally non-existent, yet it must be severed.'
