9.33

如是福智，略有六種；一一分別。應知無量者，景云：今約六度略辨福智有其六種，一一福智若廣分別應知無量。

Regarding 'Such merit and wisdom are briefly of six kinds; if differentiated one by one, they should be known to be immeasurable': Jing says: Now, briefly discerning merit and wisdom with reference to the six perfections, there are six kinds; if each merit and wisdom is extensively differentiated, they should be known to be immeasurable.
