[744] Bhāradvāja, this thought occurred to me: 'What if I, clenching my teeth against my teeth and pressing my tongue against the palate, were to beat down, constrain, and torment the mind (citta) with the mind?' So indeed, Bhāradvāja, clenching my teeth against my teeth and pressing my tongue against the palate, I beat down, constrained, and tormented the mind with the mind. And, Bhāradvāja, as I was beating down, constraining, and tormenting the mind with the mind, with teeth clenched against teeth and tongue pressed against the palate, sweat streamed from my armpits. Just as, Bhāradvāja, a strong man, seizing a weaker man by the head or seizing him by the shoulders, might beat him down, constrain him, and torment him, even so, Bhāradvāja, as I was beating down, constraining, and tormenting the mind with the mind, with teeth clenched against teeth and tongue pressed against the palate, sweat streamed from my armpits. And though my energy (vīriya) was aroused and unflagging, Bhāradvāja, and my mindfulness (sati) was established and unmuddled,¹ yet my body was overwrought and uncalmed, for I was overwhelmed by that very painful striving (padhāna).
