"Now I lay me down, to sleep"

From Samuel Johnson "On Sleep":

—Pallas pour’d sweet slumbers on his soul;
And balmy dreams, the gift of soft repose,
Calm’d all his pains, and banish’d all his woes. POPE.

If every day did not produce fresh instances of the ingratitude of mankind, we might, perhaps, be at a loss, why so liberal and impartial a benefactor as sleep, should meet with so few historians or panegyrists. Writers are so totally absorbed by the business of the day, as never to turn their attention to that power, whose officious hand so seasonably suspends the burden of life; and without whose interposition man would not be able to endure the fatigue of labour, however rewarded, or the struggle with opposition, however successful.  ....

Sleep is necessary to the happy to prevent satiety, and to endear life by a short absence; and to the miserable, to relieve them by intervals of quiet. Life is to most, such as could not be endured without frequent intermission of existence....

Sleep, therefore, as the chief of all earthly blessings, is justly appropriated to industry and temperance; the refreshing rest, and the peaceful night, are the portion only of him who lies down weary with honest labour, and free from the fumes of indigested luxury; it is the just doom of laziness and gluttony, to be inactive without ease, and drowsy without tranquillity.

Sleep has been often mentioned as the image of death; “so like it,” says Sir Thomas Brown, “that I dare not trust it without my prayers:” their resemblance is, indeed, apparent and striking; they both, when they seize the body, leave the soul at liberty: and wise is he that remembers of both, that they can be safe and happy only by virtue.
