22.471

又彼空解脫門，為依止故，名無所為等者，此約三解脫門，配釋經中所說無所為等，其義可知。於彼愛樂，數修習故，得善解脫者，於彼無所為無愛樂修習故得有學解脫。一切隨眠，永滅盡故，心善解脫者，得無學解脫。

Regarding 'Furthermore, because that gate of liberation of emptiness is the basis, it is called without purpose' and so forth: this correlates with the three gates of liberation to explain 'without purpose' and so forth spoken in the sūtra; its meaning can be known. 'Because of affection and frequent cultivation of that, one attains good liberation' means that by cultivating without purpose and without affection toward that, one attains the liberation of a learner (śaikṣa). 'Because all latencies are perpetually extinguished, the mind is well liberated' means that one attains the liberation of a non-learner (aśaikṣa).
