The right brain vagus nerve connection to the lower body cuts off from the effects of phonetic literacy. The result is mechanistic materialism and the naturalistic sciences from the loss of formal and final cause once enough people are affected from print-press grammar.

People that meditate today have no idea they're supposed to generate and work with energy during meditation because the mind-body connection has been cut.
