When he composed The Narrow Road to the Deep North he was a serious student of Zen Buddhism setting off on a series of travels designed to strip away the trappings of the material world and bring spiritual enlightenment. He wrote of the seasons changing, of the smell of the rain, the brightness of the moon and the beauty of the waterfall, through which he sensed the mysteries of the universe. These travel writings not only chronicle Basho's perilous journeys through Japan, but also capture his vision of eternity in the transient world around him.
