I saw my soul at rest upon a day
As a bird sleeping in the nest of night,
Among soft leaves that give the starlight way
To touch its wings but not its eyes with light;
So that it knew as one in visions may,
And knew not as men waking, of delight.
This was the measure of my soul's delight;
It had no power of joy to fly by day,
Nor part in the large lordship of the light:
But in a secret moon-beholden way
Had all its will of dreams and pleasant night,
And all the love and life that sleepers may.
