起信論註 1.18

1.18

論所言不空者已顯法體空無妄故　（述曰。此下第二顯不空義。於中有三。初牒前空由明妄空。方顯不空真實體故）。

Treatise: What is called non-empty is because it has already revealed that the essence of dharmas is empty and devoid of delusion... (Commentary: Below this is the second part, revealing the meaning of non-emptiness. Within this there are three parts: first, repeating the preceding emptiness, whereby by clarifying that delusion is empty, it then reveals the real essence of non-emptiness.)
