This text consists of three parts: Sashimogusa, parts 1 and 2, and, added later and sandwiched in between them, the Mikakimori. The Sashimogusa is in the form of a letter addressed to a certain daimyō. A variant, the Seikidō manuscript (published as Hakuin Oshō Suiji [Reverend Hakuin’s sermons]; Minyūsha; 1913) records the recipient as “His highness, a certain Kyūshū daimyō.” The Kyūshū daimyō with whom Hakuin had the closest relations was Nabeshima Naotsune (1702-1749), the fourth daimyō of the Hizen Hasunoike domain and the recipient of Hakuin’s Oradegama, part 1.It is likely that during his sixties Hakuin sent a missive to the lord, and that this was later revised into the form of the present Sashimogusa and Mikakimori and published in 1761.
