[143] Setting at Sāvatthī. … "Bhikkhus, I will teach you one who dwells in negligence (pamādavihārī) and one who dwells in diligence (appamādavihārī). Listen to that. And how, bhikkhus, is one a dweller in negligence? Bhikkhus, when one dwells without restraint over the eye faculty, the mind (citta) is soiled among forms cognizable by the eye. For one whose mind is soiled, there is no gladness (pāmojja); when there is no gladness, there is no rapture (pīti); when there is no rapture, there is no tranquility (passaddhi); when there is no tranquility, one dwells in suffering (dukkha); the mind of one who suffers does not become concentrated; when the mind is unconcentrated, dhammas do not become manifest; because dhammas do not become manifest, one is reckoned simply as 'one who dwells in negligence.' … Bhikkhus, when one dwells without restraint over the tongue faculty, the mind is soiled among tastes cognizable by the tongue; for one whose mind is soiled … one is reckoned simply as 'one who dwells in negligence.' … Bhikkhus, when one dwells without restraint over the mind faculty, the mind is soiled among dhammas cognizable by the mind. For one whose mind is soiled, there is no gladness; when there is no gladness, there is no rapture; when there is no rapture, there is no tranquility; when there is no tranquility, one dwells in suffering; the mind of one who suffers does not become concentrated; when the mind is unconcentrated, dhammas do not become manifest; because dhammas do not become manifest, one is reckoned simply as 'one who dwells in negligence.' Thus, bhikkhus, is one a dweller in negligence."
