A beautiful part of The Sleepers from Leaves of Grass.

I too pass from the night,

I stay a while away, O night, but I return to you again, and love you.

Why should I be afraid to trust myself to you?

I am not afraid—I have been well brought forward by you;

I love the rich running day, but I do not desert her in whom I lay so long,

I know not how I came of you, and I know not where I go with you—but I know I came well, and shall go well.

I will stop only a time with the night, and rise betimes;

I will duly pass the day, O my mother, and duly return to you.
