Closer to Non-Duallity

I am continuing to read Andrew Holecek's Preparing to Die. Holecek describes how the stages of dissolution mirror a kind of edging toward a non-dual relationship with mind. The first senses to weaken and dissolve during the death stages are the eyes, followed by ears, nose, tongue and sense of touch. These senses, according to Holecek, are less and less dualistic, because they convey more proximity than distance, and more of a sense of now-ness and totality as opposed to the dualistic "near vs far", "us vs them". Perhaps one way of putting this might be to say that eyes are designed (by evolution perhaps) to see the hard edges of things and detect movement and deviation. Eyes woould be more sensitive to difference and would define differences through mental categories.Skin, on the other hand, is more related to the sense of closeness and proximity between my body and another's, which in turn evokes the notion of interconnection.
   What I find intriguing about this hypothesis is the idea that perhaps the entire civilization and education is built around the eyes. Bentham (as you might recall from the writings of Foucault) talked about the idea of the eye as a kind of symbol of 360 degree surveillance: both looking at others and looking at ourselves. When the eyes dominate a civilization, there is no need for external force, since we become our own watch-people. As people age and their bodies start to weaken, they can no longer sustain the energy that's required of hyper-vigilance or trying to "measure up" to society's requirements, such as the need to compete for scarce resources and titles. As a result, they may start to turn more inward and develop a more non-dualistic approach toward life, where letting go becomes a natural aspect of the body going into a slow decline. But who is to say that this is bad or a sign of "decay"? Perhaps this approach is closer to a more authentic wisdom.
