Love, from its awful throne of patient power
In the wise heart, from the last giddy hour
Of dread endurance, from the slippery, steep,
And narrow verge of crag-like agony, springs
And folds over the world its healing wings.
Percy Bysshe Shelley, Mary Wollstonecraft Godwin Shelley (1855). “The Poetical Works of Percy Bysshe Shelley: In Three Volumes”, p.441
