It was full of pop-psych and attitude adjustments, Greek values and the need and desire to toss rationality out the window in favor of finding that indefinable quality that resembles Tao more than anything else. 
 It's a good book, perhaps slightly dated, but enjoyable for what it was... a celebration of insanity as a better way to live live. You know, a 70's book. :) 
 Still, the novel is good for an exploration of self, assuming that this is one of the first novels you've read on the subject of an examined life.
