http://en.wikipedia.org/wiki/Ring_of_Fire_%28song%29 >Although "Ring of Fire" sounds somewhat ominous, the term refers to falling in love – which is what June Carter was experiencing with Johnny Cash at the time. Some sources claim that Carter had seen the phrase "Love is like a burning ring of fire," underlined in one of her uncle A. P. Carter's Elizabethan books of poetry. She worked with Kilgore on writing a song inspired by this phrase as she had seen her uncle do in the past. She had written: "There is no way to be in that kind of hell, no way to extinguish a flame that burns, burns, burns". >Cash's first wife, Vivian Liberto, offers a different conception of "Ring of Fire" in her book I Walked the Line. She contends that June Carter Cash was not a co-writer of the song: "To this day, it confounds me to hear the elaborate details June told of writing that song for Johnny. She didn't write that song any more than I did. The truth is, Johnny wrote that song, while pilled up and drunk, about a certain private female body part. All those years of her claiming she wrote it herself, and she probably never knew what the song was really about."
