[445] And how does a bhikkhu dwell contemplating the mind in the mind (citta) internally?
Here a bhikkhu understands a mind with lust (sarāga) thus: 'My mind has lust'; or he understands a mind without lust (vītarāga) thus: 'My mind is without lust.' He understands a mind with hatred (sadosa) thus: 'My mind has hatred'; or he understands a mind without hatred (vītadosa) thus: 'My mind is without hatred.' He understands a mind with delusion (samoha) thus: 'My mind has delusion'; or he understands a mind without delusion (vītamoha) thus: 'My mind is without delusion.' He understands a contracted mind (saṅkhitta) thus: 'My mind is contracted'; or he understands a distracted mind (vikkhitta) thus: 'My mind is distracted.' He understands an exalted mind (mahaggata) thus: 'My mind is exalted'; or he understands an unexalted mind (amahaggata) thus: 'My mind is not exalted.' He understands a surpassable mind (sa-uttara) thus: 'My mind is surpassable'; or he understands an unsurpassable mind (anuttara) thus: 'My mind is unsurpassable.' He understands a concentrated mind (samāhita) thus: 'My mind is concentrated'; or he understands an unconcentrated mind (asamāhita) thus: 'My mind is unconcentrated.' He understands a liberated mind (vimutta) thus: 'My mind is liberated'; or he understands an unliberated mind (avimutta) thus: 'My mind is not liberated.'
He cultivates that sign (nimitta), develops it, makes much of it, and determines it well; having cultivated that sign, developed it, made much of it, and determined it well, he directs the mind to the mind externally.
