5.555

述曰：釋頌後半中初句，成無學竟居解脫道中，此意從彼無間道斷已，解脫道中便得解脫更不為拘。

The Commentary states: Explaining the first line of the second half of the verse: having completed the state of an aśaikṣa and dwelling in the path of liberation, after this manas has been severed by that uninterrupted path (ānantarya-mārga), in the path of liberation it thereupon attains liberation and is no longer bound.
