論。云何為二至性功德故　述曰。此開章略辨也。言如實者。真體不無故。所言空者。真體無妄故。究竟顯實者。由妄空無極顯真故。以無妄相能總顯實故。說如實名為空也。言不空者。具體相故。此性功德言無漏者。無離斷等及念漏故。是即如實具有自體及性功德。故名不空。

Treatise: "What are the two? […] inborn virtues." Commentary: This opens the headings and briefly discerns them. Saying "as it truly is" means that the true essence is not non-existent. Saying "empty" means that the true essence is devoid of delusion. "Ultimately revealing the real" means that because delusion is empty and non-existent, the true is supremely revealed. Because the absence of deluded attributes can universally reveal the real, it is said that "as it truly is" is called empty. Saying "not empty" means that it possesses essence and attributes. These inborn virtues being called "untainted" means that they are free from severance and cessation as well as the taint of thought. That is, as it truly is, it possesses its own essence and inborn virtues; hence, it is called not empty.
