"Bhikkhus, for a bhikkhu practicing in accordance with the Dhamma (dhammānudhammapaṭipanna), this is what accords with the Dhamma: that he should dwell contemplating non-self (anattā) in form … in feeling (vedanā) … in perception … in volitional formations … that he should dwell contemplating non-self in consciousness. Dwelling contemplating non-self in form … in feeling … in perception … in volitional formations … dwelling contemplating non-self in consciousness, he fully understands form … feeling … perception … volitional formations … he fully understands consciousness. Fully understanding form … feeling … perception … volitional formations … fully understanding consciousness, he is freed from form, freed from feeling, freed from perception, freed from volitional formations, freed from consciousness; he is freed from birth, aging, death, from sorrow, lamentation, pain, grief, and despair; he is freed, I say, from suffering (dukkha)."
