Touch
Touch is, in a sense, the most intimate of the physical senses.
The skin must be directly against an object to touch it. There
is no intermediary medium, like sound for hearing or light for
seeing. So this subtle capacity is a very intimate one. Accurately
speaking, it is sensing Essence by being Essence. It is the most
direct way of perception. This capacity of touch, connected with
the belly center, is very intimately connected with the embodiment
of Essence. It is the body center; its mode of perception is embodiment.
Here, perception as touch, and being, are the same act. So this
capacity is the most important one. (Essence, pg 131)
