起信論疏筆削記 3.14

3.14

若取下，二、別示也。血脈相承者，但約迷本一心，邐迆生起不斷絕義，更不旁說真如本覺，故云一向等。略八重者，廣則十四故。以真如門及覺義，非是生起倫次故。生滅門不覺義，全體是業相故、智相相續皆法執故、執取計名皆我執故。由是相從，略成八也。

The words from 'If taking' onward form the second part, which specifically demonstrates [this]. 'Lineage succession' only considers the continuous arising through gradual stages of delusion regarding the fundamental One Mind, without branching off to explain tathatā and original enlightenment; hence it says 'exclusively', and so forth. 'Abridged into eight levels' is because in full there are fourteen: the gate of tathatā and the meaning of enlightenment do not belong to the sequential stages of arising; the meaning of non-enlightenment within the gate of arising and ceasing is in its entirety the mark of karma; the mark of cognition and continuation are both attachment to dharmas; and grasping and reckoning names are both attachment to the self. By grouping these accordingly, they are abridged into eight.
