Two men navigate the tension between the pursuit of spiritual enlightenment and the chaotic impulses of the mid-1950s counterculture. Ray Smith, a writer seeking truth, aligns himself with the charismatic Japhy Ryder, a poet and scholar of Buddhism. Together, they attempt to reconcile the ascetic ideals of Zen with the hedonistic realities of San Francisco's bohemian scene. The narrative follows their physical movement from urban poetry circles to the rugged isolation of the High Sierras, documenting their internal and external conflicts as they struggle to maintain spiritual focus amidst social excess.

The prose is often analyzed for its spontaneous, rhythmic quality that mirrors the characters' search for authenticity. Readers generally appreciate the book for its historical significance in documenting the mid-century American interest in Eastern philosophy.
