Some stillness restores you and some only pauses you, and from the outside the two are almost impossible to tell apart. One settles the nervous system; the other just takes it offline for a while. The difference rarely announces itself — you notice it later, in whether you come back with anything or simply come back.

Not every calm body has stopped scanning. From the outside, the quiet looks like rest — the body relaxed, the breath slow. But quiet comes from different places, and they don't feel the same.
