瑜伽師地論略纂 7.31

7.31

'Revealing the initial higher training in morality up to being causes and conditions for dwelling': this explains the two kinds of dwelling, sequentially serving as causes and conditions. The initial meaning is that the higher prātimokṣa morality can serve as the dwelling for dhyāna morality and the mind of higher expedient concentration; after the mind of expedient concentration, it can serve as the dwelling for the fundamental concentrated mind and higher wisdom born of cultivation—these are called the causes and conditions for the first two dwellings. Because prātimokṣa morality induces concentration morality and concentration, and the initial expedient concentration induces fundamental concentration and wisdom born of cultivation, this very training in dhyāna morality subsumed simultaneously by intermediate wisdom and concentration can serve as the causes and conditions for the dwelling of both undefiled concentration and wisdom; this is called the second two dwellings. The word 'intermediate' means that the concentration and wisdom produced after initial morality and concentration serve as the prior cause before undefiled concentration and wisdom; hence it is called 'intermediate'.
