My love has made me selfish. I cannot exist without you – I am forgetful of every thing but seeing you again – my Life seems to stop there – I see no further. You have absorb’d me. I have a sensation at the present as though I was dissolving – I should be exquisitely miserable without the hope of soon seeing you…I have been astonished that Men could die Matyrs for religion – I have shudder’d at it – I shudder no more – I could be martyr’d for my Religion – Love is my religion – I could die for that – I could die for you.
John Keats in a letter to Fanny Brawne, October 13, 1819
