19.508

所以者何已下，第二微細門別解。於中，先舉前四因即舉外執，以後辨第五因直舉理教，明諸愚夫為名言所縛。

From 'Why is this?' downwards is the second, specific explanation of the subtle approach. Therein, first it cites the first four causes, namely citing external attachments; afterwards it discerns the fifth cause, directly citing principle and teaching to clarify that all foolish worldlings are bound by verbal conventions.
