Thanks, Akvan.
I had not read the kama sutta that you quoted. It is VERY long.
We need to be very careful about the descriptions in various suttas. Some of them discuss just jhana in general, which seem to be anariya jhana. But a few suttas like the Jhana Sutta that you quoted refer clearly to Ariya jhanas.
I found the following sutta which clearly state the difference between Ariya and anariya jhanas. I need to add this sutta reference to one of those posts at the website that I referred to.
Paṭhamanānākaraṇa Sutta (AN 4. 123): “ Idha, bhikkhave, ekacco puggalo vivicceva kāmehi vivicca akusalehi dhammehi savitakkaṃ savicāraṃ vivekajaṃ pītisukhaṃ paṭhamaṃ jhānaṃ upasampajja viharati. So tadassādeti, taṃ nikāmeti, tena ca vittiṃ āpajjati. Tattha ṭhito tadadhimutto tab¬bahu¬la-vihārī aparihīno kālaṃ kurumāno brahma¬kāyikā¬naṃ devānaṃ sahabyataṃ upapajjati. Brahma¬kāyikā-naṃ, bhikkhave, devānaṃ kappo āyuppamāṇaṃ. Tattha puthujjano yāvatāyukaṃ ṭhatvā yāvatakaṃ tesaṃ devānaṃ āyuppamāṇaṃ taṃ sabbaṃ khepetvā nirayampi gacchati tiracchā¬na¬yonimpi gacchati pettivisayampi gacchati. Bhagavato pana sāvako tattha yāvatāyukaṃ ṭhatvā yāvatakaṃ tesaṃ devānaṃ āyuppamāṇaṃ taṃ sabbaṃ khepetvā tasmiṃyeva bhave parinibbāyati. Ayaṃ kho, bhikkhave, viseso ayaṃ adhippayāso idaṃ nānākaraṇaṃ sutavato ariyasāvakassa assutavatā puthujjanena, yadidaṃ gatiyā upapattiyā sati.”
Translated: “There is the case where an individual, withdrawn from sensuality (kāma), withdrawn from akusala, enters & remains in the first jhana: rapture & pleasure born from withdrawal, accompanied by directed thought & evaluation. He savors that, longs for that, finds satisfaction through that. Staying there—fixed on that, dwelling there often, not losing the jhana—then when he dies he is born with the devas of Brahma’s retinue. The devas of Brahma’s retinue, monks, have a life-span of an eon. A run-of-the-mill person having stayed there, having used up all the life-span of those devas, goes to hell, to the animal realm, or to the state of the hungry ghosts. But a disciple of the Blessed One, having stayed there, having used up all the life-span of those devas, attains Parinibbana. This, monks, is the difference, this the distinction, this the distinguishing factor, between a Noble disciple and a normal person who had not heard the Noble Truths (assutavatā puthujjanena), in regards to the gati and birth.”
I hope this answers your root question. As I discussed in those posts at the website, when one attains the first Ariya jhana, one has become an Anagami. He/she will be born in that brahma realm and will attain Parinibbana there, as clearly stated in the above sutta.
In other words, kama raga is to be completely REMOVED to get to the first Ariya Jhana. It is only temporarily suppressed (vikkhambana pahana) for the anariya jhana.
