In <i>Spirit Boxing</i>, Weaver revisits his working class core. The veteran of fifteen years as a factory worker in his native Baltimore, he mines his own experience to build a wellspring of craft in poems that extend from his life to the lives that inhabit the whole landscape of the American working class. He writes with an intimacy that is unique in American poetry, and echoes previous comparisons of his oeuvre to that of Walt Whitman. The singularity of his voice resonates here through the prism of his realization of self through a lifelong project of the integration of American and Chinese culture. The work is Daoist in influence and structure as it echoes both a harmonic realization of context and the intuitive and transcendent dance of body, mind, and spirit.
