Hi Stevie, I haven't read the books either.

My understanding is that it is the exact working of karma which is unconjecturable - as Aloka-D has said this means viewing karma as a punishment system or being fixed and getting into dialogues, with yourself and/or others about karma causing this or that in someone's life ( in general trying to use the concept of karma as an explanation ) is missing the point.
This is different to the understanding that can be gained from seeing that how we experience our world depends on our actions; and therefore we need to pay attention to our actions ( as the example from the book which you quoted above shows using sexual misconduct as an action ).
I know his articles have been quoted many times here at BWB - the articles from Ken Mcleod which can be read at his website Unfettered Mind ... in particular this one " Karma does not explain anything " are very good and relevant. http://www.unfetteredmind.org/karma-two-approaches/3
I used these articles when I ran groups for woman experiencing domestic violence and found them very empowering and useful.
