Very good provocative thoughts for life religious and meaning of your life is this cosmos
Watts does repeat himself about the yin and yang of life at times but it correlates to what he talks about in that specific lecture. Nevertheless, this lecture runs deep into a beautiful view of the world and the individual. It fits well with "Out of Your Mind." I recommend OYM first then this one. Both are equally interesting that touch different topics. Highly recommended!
The book / lectures are great for those who are seeking Satori. Listen and see if you can find it or if you should seek it :)
Challenge your understanding of the world and just have fun :)
If you have been doing meditation for even a few weeks, this books as a must read to explain some of the "thoughts" so to speak that are whirling around in your mind as you get deeper into practice. So glad I found this one.
