瑜伽師地論略纂 7.87

7.87

第十二段一頌釋中：一、住皆無愛；二、戲論皆無愛；三、踰牆離愛；四、踰塹離愛。故說阿羅漢永離貪愛，由四相故，遊諸世間，天人不識。

In the explanation of the twelfth section, one verse: first, abiding is entirely free from craving; second, conceptual proliferation is entirely free from craving; third, scaling the wall and abandoning craving; fourth, crossing the moat and abandoning craving. Therefore it is said that the arhat is forever free from craving; because of these four characteristics, he roams through the worlds, and gods and humans do not know him.
