==Structure and content== Essays in Idleness comprises a preface and 243 passages, varying in length from a single line to a few pages. Kenkō, a Buddhist monk, writes about Buddhist truths, and themes such as death and impermanence prevail in the work, although it also contains passages devoted to the beauty of nature as well as some accounts of humorous incidents. The original work was not divided or numbered; the division dates to the 17th century.
