In Our Time on the Bhagavad Gita. I've read it (I'm one of the people who boosted the numbers of the Penguin Classics sales figures quoted at the end).
It's an interesting text, but there's one bit that really struck me as being a bit, I dunno, broken:
" I am all-powerful Time which destroys all things, and I have come here to slay these men. Even if thou dost not fight, all the warriors facing thee shall die.
Airse therefore! Win thy glory, conquer thine enemies, and enjoy thy kingdom."
Wait, what? Everything you do is fundamentally futile, therefore get your ass out there and fight?
