25.81

「廣說諸道至謂三餘道」者，此下大文第三明諸道差別。就中，一明四道差別、二明四種通行、三明菩提分法、四明四種證淨、五明正智解脫、六明厭離通局。此即第一明四道差別。舉廣問略及釋可知。

Regarding "Fully explaining the paths [...] refers to the other three paths": from here down is the third major text, explaining the distinctions among the paths. Within this, there are: 1. explaining the distinctions among the four paths; 2. explaining the four modes of progress; 3. explaining the factors of awakening; 4. explaining the four purities through realization; 5. explaining right knowledge and liberation; 6. explaining the universal and restricted aspects of revulsion. This is the first, explaining the distinctions among the four paths. Raising the extensive and asking about the brief, as well as the explanation, can be understood.
