Discussion
I want to read more about Watts, which book would you recommend me?
“The Book: On The Taboo Against Knowing Who You Are” is the best place to start 
Thanks!! I definitely will take a look
You can also listen to the Alan Watts - Out of Your Mind album of lectures. There are also a bunch of TV series on youtube
