[421] Then, Aggivessana, this thought occurred to me: 'Why should I not meditate in the breathless meditative absorption (appāṇaka jhāna)?' So, Aggivessana, I stopped the in-breaths and out-breaths through my mouth, through my nose, and through my ears. When the in-breaths and out-breaths were stopped through my mouth, through my nose, and through my ears, violent winds carved up my belly. Just as, Aggivessana, a skilled cattle-butcher or a cattle-butcher's apprentice might carve up a belly with a sharp butcher's knife, even so, Aggivessana, when the in-breaths and out-breaths were stopped through my mouth, through my nose, and through my ears, violent winds carved up my belly. And, Aggivessana, my energy (vīriya) was aroused and unflagging, my mindfulness (sati) was established and unconfused; yet my body was overwrought and not tranquil, being overwhelmed by that very painful striving. But, Aggivessana, even such painful feeling (vedanā) as had arisen in me did not persist, occupying my mind (citta).
