"There is the case where a meditator — quite withdrawn from sensuality, withdrawn from unskillful states — enters and remains in the First Absorption: rapture [piti, happiness] and pleasure [sukha, joy = pleasant sensation, physical pleasure, antonym of dukkha] born from withdrawal [of the mind from the Five Mental Hindrances], accompanied by applied attention and sustained attention [vitakka and vicara]. One permeates and pervades, suffuses and fills this very body with the rapture [mental pleasure] and bliss [physical pleasure] born of withdrawal. Nothing in this entire body remains unpervaded by the rapture and bliss born of withdrawal.
"Moving further, with the stilling of applied and sustained attention, one enters and remains in the Second Absorption: rapture and bliss born of concentration, unification of mind, free of applied and sustain attention — internally collected. One permeates and pervades, suffuses and fills this very body with the rapture and bliss born of concentration. There is nothing in this entire body unpervaded by rapture and bliss born of concentration.
"With the fading of rapture, one remains equanimous, mindful, and clearly comprehending (attentive and alert, sati-sampajanna), and experiences pleasure with the body. One enters and remains in the Third Absorption, which the Noble Ones (the ariyas, enlightened ones) declare, 'Happily abides the equanimous and mindful person.' One permeates and pervades, suffuses and fills this very body with bliss, so that there is no part of this entire body unpervaded by bliss.
"Then with the abandoning of pleasant and unpleasant sensation (sukha and dukkha = pleasure and pain) — as formerly elation and grief were abandoned — one enters and abides in the Fourth Absorption. It is a state purified by equanimity and mindfulness, having abandoned pleasure and pain. The body is permeated with a pure, bright awareness with no part of the entire body unpervaded by pure, bright awareness.
