To the deep caverns of the rock

“In time, of course, Paul's day world ceased to be flat, and became a huge ball. At this stage the universe was more like a dumpling than a sandwich. Vaguely Paul still conceived the three levels of existence. The nether night was deep down within the ball of the day world. The starry night was all around it.

Are we human scientists comparably blinkered?”

“When the moon comes up, I go down
For the first time
There’s a garden deep, deep in my heart
But it’s blossomed for the last time”
