Wow. The author of this book calls himself an arhat. That is, shall I say, presumptuous? Not what I think I would look for in a Buddhist teacher (though, full disclosure, I practice Buddhism with a school I am very happy with so already have some opinions on the subject).

His whole schtick is "plain talk about enlightenment". I agree that it "sounds" egotistical, but if someone really had attained arhatship, and thought that the best way to promote spiritual training was to talk about it in a plain way, I don't think he's being unreasonable. And his lineage confirms his attainment.

Can't tell what his lineage is from what I have read.

The temple that I belong to was founded in Japan. The honorifics we use to describe our High Priest and other priests are never used by then to describe themselves. That posture is consistent in Japanese society in general, not just the sect of Buddhism I belong to. So this does seem very strange to me.
