"Johnny Cash kept what he called a Ring of Fire in his home. What was he referring to? "

He referred to his and his wife's love for one another as a ring of fire, but he also kept a circular bed in the house that he also referred to as his "ring of fire"

Thanks for the reply lydia, you are partially correct, however, I apologize in that the original question is worded incorrect. It should have read.

“Johnny Cash kept what he called his burning Ring of Fire in his home. What was he referring to? "

The answer I’m looking for is a physical item, but it is not the bed.

is it his wedding band?

If I remember correctly (doubtful) Johnny and the woman (future wife) he wrote the song for were both married to other people, when they met and fell in love.
