I think he was talking about his career, his love of music. Big Log is his life's chronicle or journal. His musical career and passion for music are what's keeping him on the road. And he's contemplating on resting for a while from touring and decide whether he should continue or retire from music altogether. I feel that his wife (Your love is cradled in knowing...) is part of this big decision "sensing too well when the journey is done there is no turning back".
