[131] How does the application (abhinīhāra) of the mind (citta) toward equanimity regarding formations (saṅkhārupekkhā) differ for the worldling (puthujjana), for the trainee (sekkha), and for one free from lust (vītarāga)?
The worldling contemplates with insight the equanimity regarding formations for the abandoning of the three fetters, for the sake of obtaining the path of stream-entry (sotāpattimagga). The trainee contemplates with insight the equanimity regarding formations, since the three fetters have been abandoned, for the sake of obtaining what is higher. One free from lust contemplates with insight the equanimity regarding formations, since all defilements have been abandoned, for the sake of a pleasant abiding in the present life (diṭṭhadhammasukhavihāra). Thus the application of the mind toward equanimity regarding formations differs for the worldling, for the trainee, and for one free from lust — in the sense of what has been abandoned and in the sense of what has not been abandoned.
