Is all that useful information? Yes – provided that it also provides an answer, a way to de-adapt and de-accumulate these states – which it does.
Your body-mind is particularly interested in and responsive to survival-critical events. It is commonplace to only think of danger-survival, but in fact every living organism has two very different kinds of survival-critical that it looks out for. The one usually overlooked is that good stuff (food, water, companionship, a cosy place to sleep, etc.) is also survival-critical. So (to make it as simple as possible) the pathway from "danger-survival-adaptation" back to normal "safe-enough" is "simply" a reversal of how attention is used. If attention is used :
congruently (i.e. for real, with no self-doubt or attempt to ignore any part of your environment), and
(if this is congruent) in a way that actively seeks – and finds – things that are survival-positive (or at least beautiful as well as being survival-neutral)
then that attention carries implicit meaning that is evident to non-cognitive parts of your nervous system. The net result is re-calibration to a world that is more the actual world you are immediately in (i.e. not what is happening in the next field, town, or country). And this recalibrated world is very likely to be safer than the imprint that has been de-calibrated.
This approach is not necessarily simple or trivial, but it is certainly straightforward. Most importantly, there are rules by which the sensory, attentive and meaning-making parts of your conscious mind have evolved to work with the body-mind (and vice versa). If these rules are applied it becomes possible (and for some things relatively easy) to de-accumulate and de-adapt imprinted survival states. What makes this process less simple and non-trivial is that the rules I have described are often contradictory to the general assumptions and ways of thinking common in modern western cultures – one kind that you and I live in.
A simplified set of these "rules" is presented in the form of practical exercises in Section 5. Section (4) condenses all the above information into something simpler and much shorter.
