In Robert Shelton's biography No Direction Home
, he gives the song a different meaning. After Dylan's motorcycle accident in 1966, when he was 25, he retreated from the spotlight. This was after he had suffered great disappointment at the reception his European and American tour dates brought. He'd been booed offstage, called a traitor, and attendance dropped at some of his concert dates. Dylan was seriously injured in the accident, and Shelton states that Dylan withdrew not only to recuperate, but to spend the time in self reflection, and with his family. He goes further, saying that the song represents Dylan's search for personal salvation.
