Nice little sneak peak to the life of samurai and Japan of samurai.

I think Tsunetomo was a bit extreme even for a samurai. In "Act now! Contemplate later." sort of way. Or maybe he was bitter. After all he stayed alive while samurais most important goal and duty is to die. At least according to him.

The "real" Japan of samurai was long past when Tsunetomo blurted out his visions. Tsunetomo maybe was one of the most hard core samurais that still existed in that time so let's give him some slack. After all guy was forced to start a new life as a monk cause some pussy had forbidden samurais to commit seppuku after your masters death.

This version of Hagakure only contais small portion of the original book. Bit less than quarter if the book is actually translated to western languages and this one was still toned down to skip some really boring parts. Editor assured that he picked the essential parts to relay the spirit and wisdom of the original book. I don't doubt that.
