大般涅槃經義記 6.41

6.41

自下第三釋顯地名，文有三句：前二離障，清淨如空，故名空地；後一攝德，寬廣如空，故曰空地。就前三中，初離癡見，後離貪、瞋，先喻後合。第三句中先喻後合，文皆可知。

From here down is the third [section], which explains and reveals the name of the ground. The text has three clauses: the first two are freedom from obstacles, pure like space, and hence named the ground of emptiness; the latter one encompasses virtues, broad like space, and hence called the ground of emptiness. Within the first two, the first is freedom from the view of delusion, and the latter is freedom from greed and anger, both first with an analogy and then the application. In the third clause, there is first an analogy and then the application; the text in each case can be understood.
