坐禪三昧經 1.82

1.82

第五法門治等分行，及重罪人求索佛，如是人等當教一心念佛三昧。念佛三昧有三種人：或初習行、或已習行、或久習行。

The fifth dharma gate remedies conduct of equal distribution [of the poisons] and those with grave transgressions seeking the Buddha. Such persons should be taught the single-minded mindfulness of the Buddha samādhi. There are three kinds of persons in the mindfulness of the Buddha samādhi: those who are beginning practitioners, those who have practiced, and those who have long practiced.
