Our strength as a species that can envision a potential future is also the source of our greatest perceptual error. We tend to freeze a picture in place as a goal and once a situation is to our satisfaction we will want to maintain that situation frozen permanently.
This mechanism is effective when we want to achieve an outcome. We see something we want to build in our minds and keep it fixed until we see the outcome achieved. This same mechanism backfires when we try to freeze a situation in place despite it being dynamic by nature.
When we picture relaxation or stress reduction, we picture permanent relaxation frozen in time. Our expectation is that we will enter a permanent state of enlightenment where everything will be calm and ok from that point on.
Our work here is about finding the variability in our physiology so we can compare it to external circumstances. We naturally physically accelerate and relax as we go through life. These up and down reactions can come from our circumstances, or it can come from our imagination. When we are reacting to our circumstances we are in alignment with what is real and reacting appropriately.
When we react with our imagination we can be reacting to fictions, and fictions can make us accelerate when it is not necessary. So our goal is not to dumb down our accelerations or artificially amp ourselves up, it is to accelerate when circumstances call for it and to rest when no acceleration is needed.
