[346] "But this abiding (vihāra), Ānanda, has been fully awakened to by the Tathāgata therein, namely: by not attending to any signs (nimitta), to enter and abide in emptiness (suññatā) internally. And if, Ānanda, while the Tathāgata is abiding in this abiding, bhikkhus, bhikkhunīs, laymen, laywomen, kings, kings' chief ministers, sectarians, and disciples of sectarians come to visit the Tathāgata, the Blessed One, then, Ānanda, the Tathāgata—with a mind (citta) slanting to seclusion (viveka), sloping to seclusion, inclining to seclusion, withdrawn, delighting in renunciation (nekkhamma), having become altogether rid of things that are grounds for the taints (āsava)—there invariably gives talk connected only with dismissing them. Therefore, Ānanda, if a bhikkhu should wish, 'May I enter and abide in emptiness internally,' then, Ānanda, that bhikkhu should steady his mind internally, settle it, unify it, and bring it to concentration (samādhi)."
