From the Beyond (Eternity) the world was created; man was created; time and space were created.
In the world: man, time and space we perceive duality, or a multiplicity. In Eternity we imagine Unity.
The ultimate duality is between Eternity and the World, between God and man, but this is a sometime thing-- until the end of time. As a creature the world will end; you, too, will end, as a creature.
But the vision of the mystic suggests that you are more than a creature. The writer of Genesis had such an inkling when he described man as made of the dust of the earth, but in the image of God. The Quakers believe there is 'that of God' in everyone.
