The Mind of the Universe I think it is incredibly arrogant to say everything is purely physical as 'I think therefore I am.'
My problem with a lot of spiritual ideas is that they tend to view humanity as separate from other life and tend to view life as separate from the rest of the cosmos.
There is lots of evidence to support that abstract and spiritual thought aid the survival of the human race in a similar way to many other evolutionary traits formed from the chaos of natural selection. The thought that these spiritual laws existed before we manifested from physical material seems like a reverse engineer of a more likely possibility.
Spirituality could very well be more important than I believe but if it is an instinct of humans to generate these concepts then surely it is that possibility that we must open our minds to. It feels easy to shut off possibilities that shatter the importance of our egos yet I think, the further we read between the lines, the more beautiful a truth we may discover.
We are no more than atoms in the physical realm and yet, like characters in a book, the formations of our atoms represent meaning, experience to some sort of cosmic reader. Perhaps this reader is the universe itself?
I hope we are all connected to something (the universe) like branches from a tree or an ice cube tray filled with the same water. Joined by some kind of greater conscious we simply can't detect and we feel separate from it. I hope when we die we may become one with the trunk of the tree and experience all the other branches (and the trunk) simultaneously and yet also, one by one.
PS I haven't looked into Bhuddism in itself a great deal, but I love Alan Watts and Zen ideas.
