The following post is from Christian:
MN 128
Now let me develop immersion in three ways.’
Handa dānāhaṁ tividhena samādhiṁ bhāvemī’ti.
I developed immersion while placing the mind and keeping it connected; without placing the mind, but just keeping it connected; without placing the mind or keeping it connected; with rapture; without rapture; with pleasure; with equanimity.
So kho ahaṁ, anuruddhā, savitakkampi savicāraṁ samādhiṁ bhāvesiṁ, avitakkampi vicāramattaṁ samādhiṁ bhāvesiṁ, avitakkampi avicāraṁ samādhiṁ bhāvesiṁ, sappītikampi samādhiṁ bhāvesiṁ, nippītikampi samādhiṁ bhāvesiṁ, sātasahagatampi samādhiṁ bhāvesiṁ, upekkhāsahagatampi samādhiṁ bhāvesiṁ.
Can we get an explanation of “keeping it connected, without placing the mind…” etc?
