「疑五相差別」者，謂疑無他世，疑無作用，疑無因果，疑無諦，疑無實，五也。

Regarding "the five distinguishing aspects of doubt (vicikitsā)": they are doubt that there is no other world, doubt that there is no function, doubt that there is no cause and effect, doubt that there are no truths, and doubt that there is no reality—these five.
