[336] Furthermore, Ānanda, a bhikkhu—not attending to the perception of forest, not attending to the perception of earth—attends to the oneness (ekatta) dependent on the perception of the base of the infinity of space (ākāsānañcāyatanasaññā). His mind (citta) leaps forth into that perception of the base of the infinity of space, becomes confident, steady, and resolved. He understands thus: 'Whatever disturbances (darathā) there might be dependent on the perception of forest, they are not present here; whatever disturbances there might be dependent on the perception of earth, they are not present here. There is present only this measure of disturbance, namely, the oneness dependent on the perception of the base of the infinity of space.' He understands: 'This field of perception (saññāgata) is empty of the perception of forest'; he understands: 'This field of perception is empty of the perception of earth. And there is present this non-emptiness, namely, the oneness dependent on the perception of the base of the infinity of space.' 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 (suññatāvakkanti) that is in accordance with reality, undistorted, and pure.
