仁王護國般若波羅蜜多經疏 2.26

2.26

Question: Earlier under the four truths it said "all are entirely empty," and here under all phenomena it says "entirely empty." What is the difference between the two passages? Answer: The earlier text referred only to the emptiness of the object; this text also includes the emptiness of cognition. Although both object and cognition are empty of intrinsic nature, to reveal that cognition illuminates suchness and that cognition is itself signless, they are explained together. Next is the second [part], going through phenomena to clarify emptiness. The text is divided into six: first, clarifying internal and external emptiness.
