Editing Miyamoto Musashi (section)

===Later life===
In the second month of 1641, Musashi wrote a work called the ''Hyoho Sanju Go'' ("Thirty-five Instructions on Strategy") for [[Hosokawa Tadatoshi]]. This work overlapped and formed the basis for the later ''[[The Book of Five Rings]]''. This was the year that his adopted son, [[Hirao Yoemon]], became Master of Arms for the Owari fief. In 1642, Musashi suffered attacks of [[neuralgia]], foreshadowing his future ill-health.

In 1643, he retired to a cave, ''[[Reigandō]]'', living as a hermit to write ''The Book of Five Rings''. He finished it in the second month of 1645. On the twelfth of the fifth month, sensing his impending death, he bequeathed his worldly possessions, after giving his manuscript to the younger brother of Terao Magonojo, his closest disciple. Musashi died in Reigandō cave around 13 June 1645 ("[[Shōhō]] 2, 19th day of the 5th month"). Allegedly, his death resulted from lung cancer.<ref>{{cite web|url=http://kendo.com/miyamotomusashi|title=Musashi Miyamoto&nbsp;– the Legend |last= Almo |first= Leif |website= Kendo.com |publisher= Scandnet AB |archive-date=26 December 2017|archive-url= https://web.archive.org/web/20171226185621/http://kendo.com/miyamotomusashi| url-status=dead | access-date=4 March 2017}}</ref> According to ''Hyoho senshi denki'' (''Anecdotes About the Deceased Master''):
{{quote|At the moment of his death, he had himself raised up. He had his belt tightened and his wakizashi put in it. He seated himself with one knee vertically raised, holding the sword with his left hand and a cane in his right hand. He died in this posture, at the age of sixty-two. The principal vassals of Lord Hosokawa and the other officers gathered, and they painstakingly carried out the ceremony. Then they set up a tomb on Mount Iwato on the order of the lord.<ref name="tokitsu" />{{rp|131}}}}
