It’s an interesting story. Kind of a mixture of several Eastern philosophies combined with practical advices/exercises for everyday life. Oh wait, I may be confused with another textbook here, the companion to this one.
On an interesting note, I don’t even have to pick up the book, to know its content. I seemed to have absorbed this a long time ago. :-) It kinda of works like that for me. Everything that fascinates me seems to stick around.
