Hi Charlie,
Nice observations. The eyes are a very useful tool and used with various techniques and have various relations within the brain etc. Most of the sensory motor cortex for instance is devoted to the hands and the head,neck ,eyes etc. This is how some of the modern somatic mind/body discipines evolved like feldenkrais,hanna somatics ,as well as yoga in all it’s forms. But generally, eyes can be useful in training our attention.At least whilst they’re open, our external attention naturally follows(like a pet monkey on a piece of string). It would merit several threads by themselves to discuss it fully. The eyes relate to the occipital region or the back end of ajna chakra or third-eye, the back of the skull. The human brain it is an extraordinary thing deeply interconnected, with billions of neural connections wwrapping round the planet many times over as many neurons as stars in our galaxy. Science is only scratching at the surface,particularly human consciousness and how to expand it. Sometimes called the human potential movement.Fascinating stuff , i agree.
And Flexpenguin,
Sounds like you’ve got a good teacher there. The jaws,eyes and nose must all have a significance in that much of our sensory experience is in their range-taste,sight,smell etc- as data-gathering sources, and as areas where prominent subtle nerves intersect and converge. . The nadis and the nostrils supposedlyhave quite an intimate connection. Ida,Pingala & sushumna converge beteen the eyebrowss at the top end of the senstive nerves at the top of the nostrils.The nose in the sensory cortex, i have read, is also supposedly connected with the perineal body/perineum and muladhara chakra.Check here for Subtle anatomy of the head.
But the jist of what i am saying is that the nervous system is all interconnected. The science of yoga is in part based on a knowledge of those connections, and there are many, and the keys /tools or practices are like levers that prize open conciousness into a more expanded state through the use and application of this spiritual knowledge.Mainstream medical science would be wise to sit up, and take note.
