[338] "Furthermore, Ānanda, a bhikkhu—not attending to the perception of the base of the infinity of space (ākāsānañcāyatanasaññā), not attending to the perception of the base of the infinity of consciousness (viññāṇañcāyatanasaññā)—attends to the singleness (ekatta) dependent on the perception of the base of nothingness (ākiñcaññāyatanasaññā). His mind (citta) enters into that perception of the base of nothingness, gains confidence, becomes steady, and is resolved upon it. He understands thus: 'Whatever disturbances there might be dependent on the perception of the base of the infinity of space, those are not present here; whatever disturbances there might be dependent on the perception of the base of the infinity of consciousness, those are not present here. There is present only this measure of disturbance, namely, the singleness dependent on the perception of the base of nothingness.' He understands: 'This field of perception is empty of the perception of the base of the infinity of space'; he understands: 'This field of perception is empty of the perception of the base of the infinity of consciousness. And there is present only this that is not empty, namely, the singleness dependent on the perception of the base of nothingness.' Thus he regards it as empty of what is not there; but as to what remains there, he understands that which is present thus: 'This is present.' Thus too, Ānanda, this is for him a descent into emptiness (suññatā) that is genuine, undistorted, and pure."
