金剛般若波羅蜜經註解 1.126

1.126

梵語阿蘭那，華言無諍。無諍者，謂離二障：一者、惑障，二者、智障。離惑則不著有相、離智則不著無相，故無諍也。

In Sanskrit 'araṇā', in Chinese 'non-contention'. Non-contention means being free from the two hindrances: first, the hindrance of delusion, and second, the hindrance of knowledge. Free from delusion, one does not attach to the mark of existence; free from knowledge, one does not attach to the mark of nonexistence; hence there is no contention.
