“Seth material” search engine (Jane Roberts)

The body maintains its vitality not only through the physical motion and agility that you perceive, but by microscopic agility, and actions within microseconds, that you do not perceive. There is as much motion, stimulation, and reaction in the interior bodily environment as the body meets through its encounters with the exterior environment. The body must now and then “flush its systems out,” run through its repertoire, raise its temperature (pause), activate its hormonal actions more strongly. In such ways it keeps its system of immunities clear. That system operates always. To some extent, it is a way that the body distinguishes between self and nonself.

There is great traffic flow in a city: A body knows how to leap out of the way in a moment’s time from an approaching car. In the interior physical environment there is far greater traffic flow. There are decisions made in periods of time so brief you cannot imagine them—reactions that are almost over before they begin, reactions so fast you cannot perceive them as the body responds to its inner reality, and to all the stimuli from the exterior environment. The body is an open system. As solid as it seems to you, there are constant chemical reactions between it and the world, electromagnetic adjustments, alterations of balance, changes of relationships—alterations that occur between the body and its relationship with every other physical event, from the position of the planets and moon and the sun, to the position of the smallest grain of sand, to the tiniest microbe in anyone’s intestine (intently).
