瑜伽師地論略纂 2.97

2.97

Regarding 'having no attachment whatsoever, definitely progressing toward excellence' in the northern continent: because they practice selflessness, they have no attachment; toward clothing, food, and the like, they do not give rise to [the thought of] 'mine'; thus they are destined for definite progress toward excellence in the future. In that continent, there is definitely karma yielding a subsequent rebirth in heaven, because prior to the contemplation of selflessness they cultivate the ten wholesome courses of action; hence it says that they will definitely attain progress toward excellence. In some places it is said that they have karma yielding a subsequent rebirth that definitely falls among the pretas, but whether this is a trustworthy statement is not certain.
