With Subha 2.16

2.16.1

Seyyathāpi, māṇava, udakarahado gambhīro ubbhidodako. Tassa nevassa puratthimāya disāya udakassa āyamukhaṃ, na dakkhiṇāya disāya udakassa āyamukhaṃ, na pacchimāya disāya udakassa āyamukhaṃ, na uttarāya disāya udakassa āyamukhaṃ, devo ca na kālena kālaṃ sammā dhāraṃ anupaveccheyya. Atha kho tamhāva udakarahadā sītā vāridhārā ubbhijjitvā tameva udakarahadaṃ sītena vārinā abhisandeyya parisandeyya paripūreyya paripphareyya, nāssa kiñci sabbāvato udakarahadassa sītena vārinā apphuṭaṃ assa.

It’s like a deep lake fed by spring water. There’s no inlet to the east, west, north, or south, and the heavens would not properly bestow showers from time to time. But the stream of cool water welling up in the lake drenches, steeps, fills, and spreads throughout the lake. There’s no part of the lake that’s not spread through with cool water.

2.16.2

Evameva kho, māṇava, bhikkhu …pe…

In the same way, a mendicant drenches, steeps, fills, and spreads themselves with rapture and bliss born of immersion. There’s no part of the body that’s not spread with rapture and bliss born of immersion.

2.16.3

yampi, māṇava, bhikkhu vitakkavicārānaṃ vūpasamā …pe… dutiyaṃ jhānaṃ upasampajja viharati.

2.16.4

So imameva kāyaṃ samādhijena pītisukhena abhisandeti parisandeti paripūreti parippharati, nāssa kiñci sabbāvato kāyassa samādhijena pītisukhena apphuṭaṃ hoti.

2.16.5

Idampissa hoti samādhismiṃ.

This pertains to their immersion.
