The Demon's Sermon on the Martial Arts: A Graphic Novel (Shambhala Publications)

From 2013

A graphic novel presentation of Japanese philosophy familiar from Buddhism, concerning making peace by eliminating distinctions, basically.  Or, as Frozen suggested, "let it go."  Accompanied by playful illustrations of the various creatures who convey its ideas, Demon's Sermon, as with any form of philosophy or self-help, will either tell you what you need to know, or it won't.  Or, just maybe, give you a little encouragement along your way.

...So no, this has nothing to do with Ra's al Ghul.
