"Monks, there are these four modes of practice. Which four? Painful practice with slow intuition, painful practice with quick intuition, pleasant practice with slow intuition, & pleasant practice with quick intuition.

"And which is painful practice with slow intuition? There is the case where a monk remains focused on unattractiveness with regard to the body, percipient of loathsomeness with regard to food, percipient of non-delight with regard to the entire world, (and) focused on inconstancy with regard to all fabrications. The perception of death is well established within him. He dwells in dependence on the five strengths of a learner — strength of conviction, strength of conscience, strength of concern, strength of persistence, & strength of discernment — but these five faculties of his — the faculty of conviction, the faculty of persistence, the faculty of mindfulness, the faculty of concentration, the faculty of discernment — appear weakly. Because of their weakness, he attains only slowly the immediacy that leads to the ending of the effluents. This is called painful practice with slow intuition.

"And which is pleasant practice with slow intuition? There is the case where a monk — quite secluded from sensuality, secluded from unskillful qualities — enters & remains in the first jhana: rapture & pleasure born of seclusion, accompanied by directed thought & evaluation. With the stilling of directed thoughts & evaluations, he enters & remains in the second jhana: 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 jhana, 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 joy & distress — he enters & remains in the fourth jhana: purity of equanimity & mindfulness, neither pleasure nor pain. He dwells in dependence on these five strengths of a learner — strength of conviction, strength of conscience, strength of concern, strength of persistence, & strength of discernment — but these five faculties of his — the faculty of conviction, the faculty of persistence, the faculty of mindfulness, the faculty of concentration, the faculty of discernment — appear weakly.
