Secondly we have to distinguish understanding. And here we have to be clear about the fact that all understanding is conveyed by man's rhythmic system, not by his system of nerves and senses. Perception, alone, is conveyed by the nerve-senses system, and we only understand a picture process, for example, because the rhythmical process regulated by the heart and the lungs proceeds through the brain fluid to the brain. The vibrations going on in the brain receive their stimulus in man's rhythmic system, and it is these vibrations that are the actual bodily conveyers of understanding. We can understand, because we breathe.
