[737] The four jhānas (jhāna):
Here a bhikkhu, quite secluded from sensual pleasures (kāma), secluded from unwholesome phenomena (dhammā), enters and dwells in the first jhāna, which is accompanied by thought (vitakka) and examination (vicāra), with rapture (pīti) and happiness born of seclusion (viveka). With the stilling of thought and examination, he enters and dwells in the second jhāna, which has internal confidence (sampasādana) and unification of mind (cetaso ekodibhāva), is without thought and without examination, with rapture and happiness born of concentration (samādhi). With the fading away of rapture, he dwells equanimous (upekkhaka), and, mindful and clearly comprehending, he experiences happiness with the body; he enters and dwells in the third jhāna, that of which the noble ones declare: "Equanimous, mindful, he dwells in happiness." With the abandoning of pleasure and the abandoning of pain (dukkha), and with the earlier disappearance of joy (somanassa) and grief (domanassa), he enters and dwells in the fourth jhāna, which is neither painful nor pleasant, with purity of mindfulness due to equanimity.
Of the four jhānas, how many are wholesome, how many unwholesome, how many indeterminate (abyākata)? … How many are with conflict (saraṇa), how many without conflict (araṇa)?
