瑜伽師地論略纂 10.8

10.8

論曰「如說種姓，最初發心、所行加行應知亦爾」者，釋曰：如種姓有前助、因義等，當知發心等亦爾。　問曰：所行加行是何？前明發心持，名行加行，今此復名所行加行。釋曰：所行、能行，兩種名異。所行之行，謂菩提分法；能行之行，謂彼發心。故前發心名行加行，今此准文中菩提分法是所行加行，兩種別也。

The treatise says: 'As gotra is explained, the initial generating of the aspiration and the undertaken preparation should be known to be likewise.' Explanation: Just as gotra has the previous meanings of aid, cause, and so forth, one should know that generating the aspiration and the rest are also likewise. Question: What is the 'undertaken preparation'? Previously, explaining the support of generating the aspiration, it was called 'practicing preparation'; now here it is again called 'undertaken preparation'. Explanation: What is undertaken and what can undertake are two different names. The practice that is undertaken refers to the factors conducive to awakening; the practice that can undertake refers to that generating of the aspiration. Therefore, the former generating of the aspiration is called practicing preparation; now here, following the text, the factors conducive to awakening are the undertaken preparation—the two are distinct.
