[341] Furthermore, Ānanda, a bhikkhu—not attending to the perception of the base of nothingness, not attending to the perception of the base of neither-perception-nor-non-perception—attends to the singleness dependent on the signless concentration of mind (animitta cetosamādhi). His mind (citta) enters into that signless concentration of mind, becomes confident, becomes steady, and is resolved upon it. He understands thus: 'This signless concentration of mind is conditioned (abhisaṅkhata) and volitionally produced (abhisañcetayita). But whatever is conditioned and volitionally produced is impermanent, subject to cessation.' Knowing thus, seeing thus, his mind is liberated from the taint (āsava) of sensuality, his mind is liberated from the taint of existence, his mind is liberated from the taint of ignorance. When it is liberated, there is the knowledge (ñāṇa): 'It is liberated.' He understands: 'Birth is destroyed, the holy life has been lived, what had to be done has been done, there is no more coming to any state of being.'
He understands thus: 'Whatever disturbances there might be dependent on the taint of sensuality, those are not present here; whatever disturbances there might be dependent on the taint of existence, those are not present here; whatever disturbances there might be dependent on the taint of ignorance, those are not present here. There is present only this amount of disturbance, namely, that connected with the six sense bases (āyatana), dependent on this very body and conditioned by life.' He understands: 'This field of perception is empty of the taint of sensuality'; he understands: 'This field of perception is empty of the taint of existence'; he understands: 'This field of perception is empty of the taint of ignorance. And there is present only this non-emptiness, namely, that connected with the six sense bases, dependent on this very body and conditioned by life.' 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, Ānanda, this is for him the descent into emptiness (suññatā) that is in accordance with reality, undistorted, pure, supreme and unsurpassed.
