[1020] For whatever concentration (samādhi) he has, Sāriputta, that is his faculty of concentration (samādhindriya). For, Sāriputta, of a noble disciple who has faith, whose energy (vīriya) is aroused, whose mindfulness is established, and whose mind (citta) is rightly concentrated, this may be expected: that he will understand thus: 'Without discoverable beginning is saṃsāra; a first point is not evident of beings roaming and wandering on, hindered by ignorance (avijjā) and fettered by craving (taṇhā). But the remainderless fading away and cessation of ignorance, the mass of darkness — this is the peaceful state, this is the sublime state, namely, the stilling of all volitional formations, the relinquishing of all acquisitions, the destruction of craving, dispassion, cessation (nirodha), Nibbāna.'
