Regarding the meaning of the sutta, it states conditioned and unconditioned realities should be separated:
For the sake of knowing qualities of dualities as they actually are.’ ‘What duality are you speaking about?’ ‘This is stress. This is the origination of stress’: this is one contemplation. ‘This is the cessation of stress. This is the path of practice leading to the cessation of stress’: this is a second contemplation. For a monk rightly contemplating this duality in this way — heedful, ardent, & resolute — one of two fruits can be expected: either gnosis right here & now, or — if there be any remnant of clinging-sustenance — non-return."
