大毘盧遮那成佛經疏 2.43

2.43

第十四「云何無諍心？謂是非俱捨」者，准梵本轉聲，云於六十心下皆合有為性之字，例可知也。謂其心不懷向背，雖先所宗習作如是見解，更聞異言，以違合理即受行之。或先以為是，聞他以為不善，即能改之。情無所執，是非俱捨。如有如是相，當知是無諍心也。覺知無記無諍之心，修諸法實相無諍之心，是彼對治也。

Fourteenth: regarding "What is the non-disputatious mind? It means relinquishing both right and wrong": according to the declensions in the Sanskrit text, below the sixty minds there should always be the words 'having as its nature', and by analogy all can be known. This means that the mind harbours neither partiality nor opposition; although one previously held such views from what one practiced and adhered to, upon hearing differing words, if they accord with reason even if contrary [to one's former view], one immediately accepts and practices them. Or if one previously considered something right, but hears that others consider it unwholesome, one is immediately able to change it. The sentiment clings to nothing, relinquishing both right and wrong. If there are such marks, one should know that it is the non-disputatious mind. Perceiving the indeterminate non-disputatious mind and cultivating the non-disputatious mind of the dharmatā of all dharmas is its antidote.
