[1224] "Venerable sir, how many dangers (ādīnava) are there for one who falls asleep with mindfulness lost, not clearly comprehending?"
"Upāli, there are these five dangers for one who falls asleep with mindfulness (sati) lost, not clearly comprehending (asampajāna). Which five? He sleeps in discomfort; he awakens in discomfort; he sees evil dreams; the deities (devatā) do not protect him; semen is emitted. These, Upāli, are the five dangers for one who falls asleep with mindfulness lost, not clearly comprehending.
"Upāli, there are these five benefits (ānisaṃsa) for one who falls asleep with mindfulness established, clearly comprehending. Which five? He sleeps in comfort; he awakens in comfort; he does not see evil dreams; the deities protect him; semen is not emitted. These, Upāli, are the five benefits for one who falls asleep with mindfulness established, clearly comprehending."
