What metaphors are used in Big Sur by Jack Kerouac?

The cabin begins as a haven and sanctuary for Kerouac from the life of drinking and crowding fans that has defined his hometown. The first three weeks he spends there he describes as the happiest three weeks of his life. Later, it is the setting for parties and Kerouac's recognition of the contrast between his solitude and what he has invited to the place. The cabin becomes a metaphor for his mental and emotional states.
