This paper examines how Lyn Hejinian’s My Life embodies a radicalexperiment with the subjective uncertainty of autobiography, indicating theperceptive response to her essay, “The Rejection of Closure.” As an “opentext” of poetic autobiography, My Life surpasses the limits of conventionalrepresentation through fragmentations, gaps, semantic shifts, and ellipticalsentences. Throughout My Life, the reader cannot expect any consistency ora coherent lyric subject, as that subject changes incessantly from the past tothe present. Revealing a strong longing for the closure of perfectcommunication, Hejinian’s autobiographical intimacy, indeed, is signified asquixotically untenable. Arguing that My Life challenges the problems ofrepresentation and expands beyond the limits of “actual representations,” thispaper describes how Hejinian crosses the boundary between poetry and prose.Ultimately, it suggests that Hejinian’s autobiography invites the reader tointerrogate the language as a pure medium for reflection
