We agree on using our brain. Our oneness can be more than physical. The only fact we exist is beyond explanation.
I really love to learn about religions. I'm not a religious person but I see the universe as really Divine or beyond what words can describe.
I "have" a God. Some call it the universe, some consider it the Godless universe and some other consider it the Divine universe. These are words trying to describe something that can't really be easily pinpoint.
Let's enjoy!
