Somehow I discovered it right at the very peak of my adventurous youth years, and it really changed me/fucked me up lol
Then I lost the book and like 10 years later a good friend gave me a huge audio library of Alan Watts. I remembered that book all of a sudden and listened to all the files, it rocked my world again. Alan Watts is most completely enjoyable to listen to, especially when it comes to his interpretation of Taoism.
