1692. Those who constitute the province of the dura mater had been the kind of people in life who did not think at all about spiritual and heavenly matters, nor did they discuss them. They were the kind who thought nothing else exists but what is earthly, even imagining what is spiritual and heavenly to be earthly-who, because of their inward insensitivity, were unable to retain any other mental image. However, they did not admit this, and if they had been compelled to confess what idea they had had of what is spiritual and heavenly, they would not have been able to say anything but that it was something earthly, not going more deeply into the matter. Nevertheless, like others, they attend services of Divine worship, pray and sing. It is these who constitute the province of the dura mater; and they are not in the class of spirits, but of guardian spirits, for which reason also their motions relate to the heartbeat.
