A friend post this on FB on spiritual but not religious books.
Could I do better?
Let me try.
1 Sam Harris Waking up. I've read this one and it is about an atheist searching for the spiritual experience through meditation and drug. Nice and honest tone.
2. The Last Lecture by Randy Pausch. Even if he was a bit overly optimistic, to try and live your dream in this limited life time is still a good meditative tool. Ask yourself what you want instead of listening of what society what it wants from you.
3. Mortality by Christopher Hitchens is his last unfinished work. It is a good book to contemplate on death.
4. The Atheist Manifesto is a thoughtful book on what atheists could do to improve the world. Couldn't get more spiritual than trying to help save the world.
5. The Little Prince by Antoine de Saint-Exupéry teaches us all lessons on life and what is important.
6. Winnie the Pooh books teach us about friendship and how to deal with disappointment.
7. The Selfish Gene by Richard Dawkins teach us that we are as a sub specie of ape could do so much to see the world as it is, instead of what we want it to be.
8. The Better Angels of Our Nature: Why Violence Has Declined by Steven Pinker make me rethink my own understanding of human nature, quite a lot tinted by religious bullshit forced fed to me when I was too young to resist. To know this nature of human is to learn how to trust humans from a neutral position.
So there you go. Here is my list of spiritual but not religious books. I think it is a good list. But it is very likely that I learned more than I think from books.
