Furthermore, as the placing of the mind and keeping it connected were stilled, he entered and remained in the second absorption, which has the rapture and bliss born of immersion, with internal clarity and mind at one, without placing the mind and keeping it connected.
Ye ca dutiye jhāne dhammā—ajjhattaṁ sampasādo ca pīti ca sukhañca cittekaggatā ca, phasso vedanā saññā cetanā cittaṁ chando adhimokkho vīriyaṁ sati upekkhā manasikāro—tyāssa dhammā anupadavavatthitā honti.

Regarding those phenomena, he meditated without getting involved or shying away, independent, untied, liberated, detached, with mind free of boundaries.
