[418] Then, Aggivessana, this thought occurred to me: 'Suppose I were to meditate in the breathless meditation (appāṇakaṃ jhānaṃ).' So, Aggivessana, I stopped the in-breaths and out-breaths through my mouth and through my nose. And when, Aggivessana, the in-breaths and out-breaths through my mouth and through my nose had been stopped, there was an exceedingly loud sound of winds escaping through my ear-holes. Just as there is an exceedingly loud sound from a smith's bellows being pumped, even so, Aggivessana, when the in-breaths and out-breaths through my mouth and through my nose had been stopped, there was an exceedingly loud sound of winds escaping through my ear-holes. Yet, Aggivessana, my energy (vīriya) was aroused and unflagging, my mindfulness (sati) was established and unmuddled; but my body was agitated and not tranquil, since I was overwhelmed by that very painful striving. But, Aggivessana, even such painful feeling (vedanā) as had arisen did not remain overpowering my mind (citta).
