Then it occurred to me, ‘Why don’t I, with teeth clenched and tongue pressed against the roof of my mouth, squeeze, squash, and scorch mind with mind?’ So that’s what I did, until sweat ran from my armpits. It was like when a strong man grabs a weaker man by the head or throat or shoulder and squeezes, squashes, and crushes them. In the same way, with teeth clenched and tongue pressed against the roof of my mouth, I squeezed, squashed, and crushed mind with mind until sweat ran from my armpits. My energy was roused up and unflagging, and my mindfulness was established and lucid, but my body was disturbed, not tranquil, because I’d pushed too hard with that painful striving. But even such painful feeling did not occupy my mind.
