I have heard that on one occasion the Blessed One was staying in Upavattana, the Mallan sal grove near Kusinarā.[1] And on that occasion, not far from the Blessed One, many monks were staying in wilderness huts: high-strung, rowdy, flighty, talkative, of loose words & muddled mindfulness, unalert, unconcentrated, their minds scattered, their faculties left wide open.

The Blessed One saw those many monks staying in wilderness huts: high-strung, rowdy, flighty, talkative, of loose words & muddled mindfulness, unalert, unconcentrated, their minds scattered, their faculties left wide open.

Then, on realizing the significance of that, the Blessed One on that occasion exclaimed:

By leaving your body unprotected, being immersed in wrong view, conquered by sloth & torpor, you go under Māra's sway. Therefore, with protected mind, ranging in right resolve, honoring right view, knowing rise-&-fall, conquering sloth & torpor, a monk leaves all bad destinations behind.
