[1601] "And how, Nandiya, is a noble disciple one who dwells in negligence (pamādavihārī)? Here, Nandiya, a noble disciple possesses unwavering confidence (aveccappasāda) in the Buddha thus: 'Thus indeed is that Blessed One … teacher of devas and humans, the Buddha, the Blessed One.' Content with that unwavering confidence in the Buddha, he does not strive further for solitude by day or for retreat (paṭisallāna) by night. As he thus dwells negligent, gladness (pāmujja) does not arise; when there is no gladness, there is no rapture; when there is no rapture, there is no tranquility; when there is no tranquility, he dwells in suffering (dukkha); the mind (citta) of one who suffers does not become concentrated; when the mind is unconcentrated, dhammas do not become manifest. Because dhammas do not become manifest, he is reckoned simply as 'one who dwells in negligence.'
"Furthermore, Nandiya, a noble disciple … in the Dhamma … in the Saṅgha … possesses the virtues dear to the noble ones — unbroken … conducive to concentration (samādhi). Content with those virtues dear to the noble ones, he does not strive further for solitude by day or for retreat by night. As he thus dwells negligent, gladness does not arise; when there is no gladness, there is no rapture; when there is no rapture, there is no tranquility; when there is no tranquility, he 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, he is reckoned simply as 'one who dwells in negligence.' It is in this way, Nandiya, that a noble disciple is one who dwells in negligence."
