“All thoughts, all passions, all delights,
Whatever stirs this mortal frame,
All are but ministers of Love,
And feed his sacred flame.”

Stanza 1.
The Dying Christian to His Soul (1712)
Context: Vital spark of heav'nly flame!
Quit, oh quit, this mortal frame:
Trembling, hoping, ling'ring, flying,
Oh the pain, the bliss of dying!

Canto V
Queen Mab (1813)

The Poet (1830)
Context: There was no blood upon her maiden robes
Sunn'd by those orient skies;
But round about the circles of the globes
Of her keen
And in her raiment's hem was traced in flame
WISDOM, a name to shake
All evil dreams of power — a sacred name.
And when she spake,
Her words did gather thunder as they ran,
And as the lightning to the thunder
Which follows it, riving the spirit of man,
Making earth wonder,
So was their meaning to her words. No sword
Of wrath her right arm whirl'd,
But one poor poet's scroll, and with his word
She shook the world.
