Most of us must learn to feel, as an artist learns to see in order to draw. All of the physiological processes of feeling and seeing can happen with no awareness at all, when the mind is wandering elsewhere. Essential to the learning process is awareness, prajna. With no awareness, we have unconscious sensations, not conscious perceptions.
The light striking the retina of the eye is the first step in seeing. A great deal more happens in the visual part of the cerebral cortex, at the back of the head, and along the pathways to it. The conscious experience of …

Intrinsic dynamics of the central vestibular system (CVS) appear to be at least partly determined by the symmetries of its connections. The CVS contributes to whole-body functions such as upright balance and maintenance of gaze direction. These functions coordinate disparate senses (visual, inertial, somatosensory, auditory) and body movements (leg, trunk, head/neck, eye). They are also unified by geometric conditions. Symmetry groups have been found to structure experimentally-recorded pathways of the central vestibular system. When related to geometric conditions in three-dimensional physical space, these symmetry groups make sense as a logical foundation for sensorimotor coordination.
