In Denis Johnson's "Jesus' Son," the protagonist expresses a sense of existential realization amidst a chaotic life. The quote highlights a moment of clarity where the trivialities of existence are overshadowed by the profound significance of simply being alive. It suggests that even experiences that seem meaningless, like "drinking a dog's tears," pale in comparison to the preciousness of life itself.

This sentiment reflects the raw and often harsh realities faced by the characters in the book. Despite their struggles and the often absurd situations they find themselves in, the underlying message is about appreciating life’s essence. The journey of the characters serves to illuminate the stark beauty and fragility of existence, reminding readers that sometimes survival is the only thing that truly matters.
