I commend to you this poem by William Stafford, which I find most appropriate for the beginning of this Advent season. It sounds the theme of wakefulness.
The poem is entitled A Ritual To Read to Each Other. It contains these lines:
For it is important that awake people be awake,
or a breaking line may discourage them back to
the signals we give — yes or no, or maybe —
should be clear: the darkness around us is deep.
