Matsuo Basho (1644-1694) was the most influential Japanese poet of his time and the undisputed master of haiku. This volume presents the complete Spanish translation of his travel diaries, texts where poetic prose and Zen philosophy intertwine in narratives set among ancient temples, remote paths, and moments of luminous everyday life interspersed with poems and notes. Through "Travel Memoirs of a Withered Bag of Bones," "Kashima Diary," "My Backpack Diary," and "Saga Diary"--along with excerpts from the legendary "Narrow Road to the Deep North"--the reader gains access to the vision of a traveler who conceived of poetry as an act of contemplation and listening. Each journey responds to a quest: relics of ancient poets, landscapes consecrated by tradition, encounters with disciples in need of a crumb of wisdom. Aguado has restored the textual architecture of these diaries with the profound singularity of his sense of poetry. The included haikus adhere to classical meter when it serves their purpose; the notes contextualize the spiritual geography without supplanting the reader's experience. Basho emerges here as he truly was: a samurai who laid down his sword to write with ink, transforming the path into writing and writing into the only journey that matters.
