I am also a fan of Douglas Harding and his teaching -- reading "On Having No Head" contributed quite a bit to my philosophical development.
I can actually still see the bookstore environs surrounding my first looking at the cover... all the way back to... <wait for it> ... <drum roll> ... 19.... EIGHTY.... SIX....
Headlessly, of course. :-)
It definitely felt a great conceptual basis for other reading material taking discussion/analysis of mind/self/conceptuality/modeling/"reality"/etc. to even greater/more-interesting depths.
