ignorance gone then no body.But when ignorance fades away and ceases with nothing left over, there is no body and no voice and no mind, conditioned by which that pleasure and pain arise in oneself.
avijjāya tveva asesavirāganirodhā so kāyo na hoti yaṃpaccayāssa taṃ uppajjati ajjhattaṃ sukhadukkhaṃ, sā vācā na hoti yaṃpaccayāssa taṃ uppajjati ajjhattaṃ sukhadukkhaṃ, so mano na hoti yaṃpaccayāssa taṃ uppajjati ajjhattaṃ sukhadukkhaṃ,
if to consider mindfulness of breath,“Mendicants, as long as there’s a body, the intention that gives rise to bodily action causes pleasure and pain to arise in oneself.
“Kāye vā, bhikkhave, sati kāyasañcetanāhetu uppajjati ajjhattaṃ sukhadukkhaṃ.
when breathing in and out and knowing you are breathing heavily or lightly.
They practice breathing in experiencing the whole body. They practice breathing out experiencing the whole body. ‘sabbakāyapaṭisaṃvedī assasissāmī’ti sikkhati, ‘sabbakāyapaṭisaṃvedī passasissāmī’ti sikkhati;
so guessing that the dīgha is dukkha and rassa is sukha.They practice breathing in stilling the body’s motion. They practice breathing out stilling the body’s motion. ‘passambhayaṃ kāyasaṅkhāraṃ assasissāmī’ti sikkhati, ‘passambhayaṃ kāyasaṅkhāraṃ passasissāmī’ti sikkhati. (1)
then the "no body" is when the kayasankharas are stilled. Which could be neither pleasure nor suffering, what doesn't mean neutral but in same level as digha and rassa but is instead factor of liberation what means "fading of ignorance".
and the breathing in and out and knowing about im breathing heavy or lightly is happen "within the individual" so the being within being are the feelings.
uppajjati here mean the feelings: dukkha and sukkha. And maybe the "stilling of kayasankhara" is the One we need listen.ajjhattaṃConcise Pali-English Dictionary by A.P. Buddhadatta Mahathera
