But that is quite profound, because it means that attentiveness is what we need. It is not attention. It is not a super-focused attention. It is more like this ambient attentiveness that lets you completely merge your horizon with the book or with your interlocutor. And when the other person experiences this deep listening -- being listened to, attended to for five minutes -- something in them also changes, and their heart rate also goes more calm. It's like co-regulation.
