[607] "Furthermore, brahmin, on whatever occasion one dwells with a mind (citta) obsessed by dullness and drowsiness (thīna-middha), overwhelmed by dullness and drowsiness, and one does not understand and does not see, as it really is (yathābhūta), the escape from arisen dullness and drowsiness — on that occasion one does not understand and does not see, as it really is, even one's own good; … one does not understand and does not see, as it really is, even the good of others; on that occasion one does not understand and does not see, as it really is, even the good of both. Then even hymns long recited do not recur to the mind, let alone those not recited.
