Books from Robert M. Pirsig and his Metaphysic

After parsing the website of FreeMind I was surprised to read there about Robert Pirsig. Especial about the recommendation on a book called Lila I never heard about that book before but seems it was published some years more early and now get sold out. Look like it has an interesting insight on some metaphysic.
The interesting there is the way of thinking and constructing personal metaphysics. It is, in his idea, kind like people who use the FreeMind-Software love to note down her work and ideas.
It seems that outside more books and people with great philosophical ideas exist as we can get before our eyes. There is realy the need to collect and group all of that existing philosophical seeds of meta-universes to give people a more easy overview and guideline. People need to have seeds from many different directions and kinds of metaphysics to develop there personal thoughts that will bring humanity to higher level of illumination.
