   Fill your bowl to the brim
   and it will spill.

   Keep sharpening your knife
   and it will blunt.

   Chase after money and security
   and your heart will never unclench.

   Care about people's approval
   and you will be their prisoner.

   Do your work, then step back.
   The only path to serenity.
-- Tao te Ching, Stephen Mitchell translation (http://www.amazon.com/dp/0061142662).

The best prescriptive book that I have found has been: http://www.amazon.com/Zen-Training-Philosophy-Shambhala-Clas...

Additionally I find that reading a good translation of the Tao helps, my personal favorite so far is: http://www.amazon.com/Tao-Te-Ching-Perennial-Classics/dp/006...
