51.42

第九「十種無著」下二門，明王子住中行。此門由無著故，能善知十法；後門由平等故，勝進學法王處法。

Ninth, from 'ten kinds of non-attachment' onward, two gates clarify the practice in the stage of the prince. In this gate, through non-attachment, one is able to skillfully know the ten dharmas; in the latter gate, through equanimity, in superior progress one learns the dharmas of the Dharma King's station.
