The Wall & The Tunnel by Eric Hepburn

There is a wall, a veil, between our world and the spirit world... the sages and prophets found ways through the wall, they brought back teachings from the spirit world. They left behind signs so that we could find our way through. Some folks who came after, got really into sign making. Some thought that the tunnels through the wall should be enlarged, decorated, celebrated... Some spent their lives making their religion's entrance look more beautiful and inviting than others' Some forgot that the signs were about getting through the wall - they just wanted to celebrate the tunnel as a beautiful place to BE.
