There is fermentation free awareness to dwell in, what is very hard to do.“And what constitutes a monk’s strength? There is the case where a monk, through the ending of the mental fermentations, enters & remains in the fermentation-free awareness-release & discernment-release, having directly known & realized them for himself right in the here & now. This constitutes a monk’s strength.
“Monks, I don’t envision any other single strength so hard to overcome as this: the strength of Māra.4 And the adopting of skillful qualities is what causes this merit to increase.”5
Here what is pleasure for monks..it substitutes the ordinary person way gotten pleasures
“And what constitutes a monk’s pleasure? There is the case where a monk—quite secluded from sensuality, secluded from unskillful qualities—enters & remains in the first jhāna: rapture & pleasure born of seclusion, accompanied by directed thought & evaluation. With the stilling of directed thoughts & evaluations, he enters & remains in the second jhāna: rapture & pleasure born of concentration, unification of awareness free from directed thought & evaluation—internal assurance. With the fading of rapture he remains equanimous, mindful, & alert, and senses pleasure with the body. He enters & remains in the third jhāna, of which the noble ones declare, ‘Equanimous & mindful, he has a pleasant abiding.’ With the abandoning of pleasure & pain—as with the earlier disappearance of elation & distress—he enters & remains in the fourth jhāna: purity of equanimity & mindfulness, neither pleasure nor pain. This constitutes a monk’s pleasure.
