第二明性非無之中，文別有四：初「眾生性不破壞」等，法說明有。二「如眾生中所有空」下，喻說明有。於中，初明虛空是有，「若使眾生無虛空」下破無成有，「以是義」下引說證有。「虛空界者是名虛空」結空為有。三「佛性如是」合喻明有。四「十住」下就人分別。有四：一明佛性佛菩薩見、二「非是」下明非凡夫二乘所見、三「是故」下明不見損、四「見佛性」下明見知益。

Within the second [part], clarifying that the nature is not non-existent, the text has four distinct parts: First, "The nature of sentient beings is not destroyed..." and so forth speaks of existence in terms of Dharma. Second, below "Just like the space within sentient beings...", it speaks of existence by metaphor. Therein, first it clarifies that space is existent; below "If sentient beings had no space...", it refutes non-existence to establish existence; below "By this reasoning...", it cites teachings to corroborate existence. "The realm of space is called space" concludes that space is existent. Third, "Buddha-nature is like this" matches the metaphor to clarify existence. Fourth, below "ten abodes", it differentiates in terms of persons. There are four points: first, clarifying that buddha-nature is seen by buddhas and bodhisattvas; second, below "It is not...", clarifying that it is not seen by ordinary beings and the two vehicles; third, below "Therefore...", clarifying the detriment of not seeing; fourth, below "seeing buddha-nature", clarifying the benefit of seeing and knowing.
