It's very beneficial that we have a nervous system to alert us to what's going on. Our nervous system communicates primarily through sensations and energy and sometimes through catastrophic thoughts. Since we tend to try to avoid what makes us uncomfortable or scared, it might be a stretch to entertain being grateful for our nervous system. Life generally is fairly hard and not what we expect, not what we would hope for, and we have to go through these times of real difficulty. We have this ongoing up and down with our nervous system. It's good to know enough to be able to recognize what's happening in ourselves, and to use our regulating practices on the spot, as well as these guided practices. We can do something for our nervous system every day, and we could appreciate ourselves for that.
