[497] Then, Prince, this occurred to me: 'Suppose I were to meditate in the breathless absorption (appāṇakaṃ jhānaṃ)?' So, Prince, I stopped the in-breaths and out-breaths through my mouth, nose, and ear-holes. When the in-breaths and out-breaths were stopped through my mouth, nose, and ear-holes, violent winds bore down upon my head. Just as, Prince, a strong man might grind into the head with a sharp point, even so, Prince, when the in-breaths and out-breaths were stopped through my mouth, nose, and ear-holes, violent winds bore down upon my head. And though my energy (vīriya) was aroused and unflagging, and my mindfulness (sati) established and unconfused, yet my body was strained and not tranquil, because I was overwhelmed by that painful striving.
