大般涅槃經集解 46.50

46.50

案道生曰：虛空亦本無也。僧亮曰：第六句也。未生是無法，虛空亦是無。若生於無者，何故不說虛空為生耶？寶亮曰：若有為法本傍無相及力者，彼起此亦起、彼滅此亦滅，正得俱時而已，云何能生於法？若俱無相及力者而得生有為法，何故不說虛空為生耶？

Daosheng says: Space is also originally non-existent. Sengliang says: This is the sixth proposition. What is not yet born is a non-existent dharma, and space is likewise non-existent. If birth arises from non-existence, why is space not said to be born? Baoliang says: If conditioned dharmas originally lacked characteristics and efficacy of their own, then when that arises this arises, and when that perishes this perishes; they would merely be simultaneous—how could they give birth to dharmas? If both lacked characteristics and efficacy yet could give birth to conditioned dharmas, why is space not said to be born?
