Your brain is a great separator. It separates stuff into categories. It separates good from bad. It separates likes from dislikes and desires from repulsions. We need it to survive. We need the thinking mechanism of the brain tool to keep us well and safe and fulfilled. It is not however a good tool for waking up, enlightenment, satori, salvation, being born again or any other way of describing the experience of heaven on earth or nirvana. You can't discover ultimate truth with a conditioned brain.
