At the end of a discussion today a friend said:
"I will leave this one with you today, dowsing in time, traveling down into the earth"
Then he walked away.
This was something he had experience with and left it out there for me to ponder until next we meet again!!
The dowsing in time would refer to time travel would be my interpretation but the sinking down in the earth in combination with that begs the question of what is the rest of the story?
