A group of neurons in the superior parietal lobe - towards the top and back of the brain - went dark. This is the region associated with processing information about space and time, and the orientation of the body in space. "It determines where the body ends and the rest of the world begins." It's orientation requires sensory input to determine it's calculus. When you block sensory inputs to this region, as you do during intense meditation, "you prevent the brain from forming the distinction between self and not-self - normal boundaries. As a result the brain seems to have no choice but to perceive the self as "endless and intimately interwoven with everyone and everything."
