瑜伽師地論略纂 12.26

12.26

論解依內外成就各有六種中，既言為內外二別，何得內中有成眾生之義，外中有自成之義？義曰：於內中雖言外眾生，意取菩薩心，故言內；於外義在有情，不存於內自就。

Regarding the treatise's explanation that internal and external accomplishments each have six kinds: since they are stated as two distinct categories, internal and external, how can the internal contain the meaning of accomplishing sentient beings, while the external contains the meaning of self-accomplishment? Answer: Although external sentient beings are spoken of within the internal, the intent focuses on the mind of the bodhisattva, and hence it is called "internal"; within the external, the meaning lies with sentient beings, and does not reside in internal self-accomplishment.
