"If fundamental...", sixth, bundling the four approaches into two meanings. That is to say, actualized enlightenment is the branch and is not separate from the root of original enlightenment; hence the text below says: "Because that which is actualized enlightenment is identical to original enlightenment." It also says: "Yet in reality there is no difference of actualized enlightenment... up to being equally identical to the one enlightenment." Branch-and-twig non-enlightenment is not separate from fundamental non-enlightenment; hence the text below says: "One should know that avidyā can produce all defiled dharmas, because all defiled dharmas are marks of non-enlightenment." However, the two enlightenments—original and actualized—differ only as essence and function; the two non-enlightenments—fundamental and branch-and-twig—differ only as coarse and subtle. How could there be function separate from essence, or coarse separate from subtle? Therefore there are only two.
