The Burnt-offering

Thrice-happy he whose heart, each new-born night,
When old-worn day hath vanished o'er earth's brim,
And he hath laid him down in chamber dim,
Straightway begins to tremble and grow bright,
And loose faint flashes toward the vaulted height
Of the great peace that overshadoweth him:
Keen lambent flames of hope awake and swim
Throughout his soul, touching each point with light!
The great earth under him an altar is,
Upon whose top a sacrifice he lies,
Burning in love's response up to the skies
Whose fire descended first and kindled his:
When slow the flickering flames at length expire,
Sleep's ashes only hide a glowing fire.
