William Blake "The Marriage of Heaven and Hell"

he true ancient belief that the world will perish in fire at the end of six thousand years - that's what I was told in Hell.
For when the Cherubim with the flaming sword will leave the guard at the tree of life, the whole creation will burn to ashes and will become holy and eternal, as the present is sinful and perishable.
The way to this is through the purification of the joys of the flesh. ‹...›
If the gates of knowledge were open, infinity would open to people. But people hid from the world and see it only in the narrow cracks of their caves. How can you know, and if in every bird that flies the air, there is an immeasurable world of delight, covered by your five senses?
