We were in Maranello a few weeks ago - a town that eats, sleeps and breathes "Ferrari". The Formula 1 shop across the street from the gates to the Ferrari factory carries, among other things, an enormous library of every book related to Ferrari's that has ever been published.
In one tiny corner though, they had some books relating to other marques - probably no more than a dozen books or so among the many thousands of volumes on Ferrari, Formula 1 etc. In any case, there I found a copy of your book (see photo), and I thought that was rather charming. It was selling there for 48 Euro - which is US$ 66.- at current exchange rates.
I think that's rather good Karma for you to have your fine book for sale less than 100 yards from the Ferrari factory.
And the concept of Karma is really hard to argue with. Everything is connected somehow through infinite chains of causation. Every thing you do effects others through this intricate web of cause and effect, and to the extent your actions are positive you influence the sum total of all actions positively, and your Karma increases.
