The author develops her narration by two clues: one is Kerouac's life experiences and the other is his social background. They have mutual influence on each other and formed a net. Every knot in the space would define time. It makes Kerouac's suffering, bewilderment and simple eternal in his life. Firm pursuit of faith being his consistent theme, he mainly focuses on “why on the road.” We call the pursuit “philosophical nostalgia”. Affected but not bound by Zen, Kerouac sticks to his belief on the road.
