For a fortnight he practiced discernment of phenomena one by one.
sāriputto, bhikkhave, aḍḍhamāsaṁ anupadadhammavipassanaṁ vipassati.
And this is how he did it.
Tatridaṁ, bhikkhave, sāriputtassa anupadadhammavipassanāya hoti.
Quite secluded from sensual pleasures, secluded from unskillful qualities, he entered and remained in the first absorption, which has the rapture and bliss born of seclusion, while placing the mind and keeping it connected.
Idha, bhikkhave, sāriputto vivicceva kāmehi vivicca akusalehi dhammehi savitakkaṁ savicāraṁ vivekajaṁ pītisukhaṁ paṭhamaṁ jhānaṁ upasampajja viharati.
And he distinguished the phenomena of the first absorption one by one: placing and keeping and rapture and bliss and unification of mind; contact, feeling, perception, intention, mind, enthusiasm, decision, energy, mindfulness, equanimity, and application of mind.
Ye ca paṭhame jhāne dhammā vitakko ca vicāro ca pīti ca sukhañca cittekaggatā ca, phasso vedanā saññā cetanā cittaṁ chando adhimokkho vīriyaṁ sati upekkhā manasikāro—tyāssa dhammā anupadavavatthitā honti.
