To -----

Percy Shelley
Music, when soft voices die, Vibrates in the memory-- Odours, when sweet violets sicken, Live within the sense they quicken. Rose leaves, when the rose is dead, Are heaped for the beloved bed; And so thy thoughts when thou art gone, Love itself shall slumber on.

Mutability

Percy Shelley
The flower that smiles to-day To-morrow dies; All that we wish to stay Tempts and then flies. What is this world's delight? Lightning that mocks the night, Brief even as bright. Virtue, how frail it is! Friendship how rare! Love, how it sells poor bliss For proud despair! But we, though soon they fall, Survive their joy, and all Which ours we call. Whilst skies are blue and bright, Whilst flowers are gay, Whilst eyes that change ere night Make glad the day; Whilst yet the calm hours creep, Dream thou--and from thy sleep Then wake to weep.

Flower in the Crannied Wall

Lord Alfred Tennyson
Flower in the crannied wall, I pluck you out of the crannies;-- I hold you here, root and all, in my hand, Little flower--but if I could understand What you are, root and all, and all in all, I should know what God and man is.
