The gates of the Mysteries are far more august and beneficial than the
gates of Paradise. The latter will not be opened to anyone who has not
first entered through the gates of the Mysteries, but these were opened
when the gates of Paradise had been closed. The latter were able to let
out those who were within, while the former only lead inside and let no
one out. It was possible to shut the gates of Paradise and so they were
shut; in the case of the Mysteries the curtain and the dividing wall
were entirely destroyed and were taken away.
