rūpa is not a-rūpa, 4 jhānas operate in rūpa

See the neighboring articles in this section on kāya and vedana, which have jhāna subsections.

Studying the article on (infinite space dimension) ākāsānañcā-(a)yatanaṃ, under formless attainments, gives detailed passages that show the specialized terminology the Buddha uses when he is being clear that the mind is divorced from the body. Especially passage MN 43 and AN 9.37.

Vism., a late Theravada treatise, did much work to spread misinformation about the 4 jhānas, and confuse the issue between rūpa, arūpa, kāya (physical body which they redefine as mental body). The article “EBT Jhāna Vs. Vism. Redefinition”.

🛇👻 The four Jhānas are not formless samādhi attainments

Not formless means you have physical body 🗸🏃‍♀️ awareness, you can feel leg pain, you can hear sounds. In 3rd and 4th jhāna, the sense of the body may subjectively be experienced as increasingly subtle, fading out. But if you can no longer hear sounds, can not kinaesthetically locate where your hands, feet, head are, have no sense of direction of up and down, then you've crossed over into formless samādhi, and you are no longer in the four jhānas.
• rūpa is not a-rūpa, 4 jhānas operate in rūpa: You think that would be obvious, but it's not a well understood point, thanks to late Theravada propaganda redefining 4 jhānas as formless (see VRJ🐍 and Jabrama🤡-jhana).
• In the 4 jhānas, the body (kāya) is physical 🗸🏃‍♀️, and feelings (vedana) by default originate and are experienced from the physical 🗸🏃‍♀️
• If you can feel leg pain and mosquito bites in the 4 jhānas, then ...
• You can 👂 hear sounds in the 4 jhānas.: Which samādhis are silent?
• If you can walk and do the jhānas in all 4 postures, then obviously you must have body awareness and can't be in a formless samādhi.
• s5👻 ākāsā-nañcā-(a)yatanaṃ: if you study the terms in the space infinitude dimension formula for patigha sañña and nanatta sañña, it's clear that it must mean in the four jhānas one is sensitive to the physical anatomical body, i.e. not in a formless samādhi.

KN Iti 72: escape from kāma is nekkhamma (right resolve’s renunciation)

KN Iti 72

♦ “tisso imā, bhikkhave, nissaraṇiyā VAR dhātuyo.	“Monks, there are these three properties for escape.
katamā tisso?	Which three?
kāmānam-etaṃ nissaraṇaṃ yadidaṃ nekkhammaṃ,	This is the escape from sensuality: renunciation.1
rūpānam-etaṃ nissaraṇaṃ yadidaṃ āruppaṃ,	This is the escape from form: formlessness.
yaṃ kho pana kiñci bhūtaṃ	And as for whatever has come into being,
saṅkhataṃ paṭiccasamuppannaṃ	is fabricated & dependently co-arisen,
nirodho tassa nissaraṇaṃ —	the escape from that is cessation.
imā kho, bhikkhave, tisso nissaraṇiyā dhātuyo”ti.	These are the three properties for escape.”

♦ “kāma-nissaraṇaṃ ñatvā,	Knowing the escape from sensuality,
rūpānañca atikkamaṃ.	& the overcoming of forms
♦ sabba-saṅkhāra-samathaṃ,	–ardent always– touching the stilling
phusaṃ ātāpi sabbadā.	of all fabrications:
♦ “sa ve sammaddaso bhikkhu,	he is a monk who’s seen rightly.
yato tattha vimuccati.	From that he is there released.
♦ abhiññā-vosito santo,	A master of direct knowing,
sa ve yogātigo munī”ti.	at peace, he is a sage gone beyond bonds.

There are those who mistakenly misinterpret this phrase as meaning the body disappears, that the mind becomes divorced from the 5 sense faculties, one can not move the body, feel pain, hear sounds in first jhāna. They base that on interpreting kāmehi as sensual pleasure objects, and that seclusion from those objects means mind separates from the physical body. This is not the case. If you look at ever single occurrence of the first jhana in the suttas, right before first jhana, it always mentions 5kg or 5niv (5 strands of sensual pleasure and/or 5 hindrances). For the mind to be divorced from the body, the Buddha has a more specific way to make that clear. See the article “rūpa is not a-rūpa, 4 jhānas operate in rūpa”.

	Note
	1. The property of form corresponds to the experience of the form of the body as present in the first four levels of jhāna (see Glossary). The property of formlessness corresponds to the formless experiences based on the fourth level of jhāna: the dimension of the infinitude of space, the dimension of the infinitude of consciousness, the dimension of nothingness, and the dimension of neither perception nor non-perception. The property of cessation is the experience of the total cessation of stress.

	♦ 879.
“For one how-arriving	♦ “kathaṃsametassa vibhoti rūpaṃ,
does form disappear?	sukhaṃ dukhañcāpi VAR kathaṃ vibhoti.
How do pleasure & pain disappear?	♦ etaṃ me pabrūhi yathā vibhoti,
Tell me this.	taṃ jāniyāmāti VAR me mano ahu”.
My heart is set
on knowing how
they disappear.”

	♦ 880.
“One not percipient of perceptions	♦ “na saññasaññī na visaññasaññī,
not percipient of aberrant perceptions,	nopi asaññī na vibhūtasaññī.
not unpercipient,	♦ evaṃsametassa vibhoti rūpaṃ,
nor percipient of what’s disappeared2:	saññānidānā hi papañcasaṅkhā”.
For one thus-arriving,
form disappears3—
for objectification-classifications4
have their cause in perception.”

2. According to Nd I, “percipient of perceptions” means having ordinary perceptions. “Percipient of aberrant perceptions” means being insane. “Unpercipient” means either having entered the cessation of perception and feeling (see AN 9:33) or the dimension of beings without perception (DN 1 and DN 15). “Percipient of what’s disappeared” (or: having perceptions that have disappeared) means having entered any of the four formless states. Of these four explanations, the last is the least likely, for as the next lines show, this passage is describing the stage of concentration practice in which one is transcending the fourth jhāna and entering the formless attainment of the infinitude of space. A more likely explanation of “percipient of what’s disappeared” would be the act of holding to perceptions of the breath and of pleasure and pain, even though these phenomena have all disappeared in the fourth jhāna (see SN 36:11, AN 9:31, AN 10:20, and AN 10:72). 3. This is the point where the meditator leaves the fourth jhāna and enters the perception of the infinitude of space.
