It is the  Hereafter.

The name probably comes from the root dua: “morning”, used to indicate what precedes the morning, that is, the night, and particularly the land of the night, the hereafter.

Pictorially, it is pictured as a star inscribed in a circle.

This proves the doctrine of a celestial (stellar) hereafter preceding the doctrine of Osiris  (earthly).

The pictures of this divinity are extremely rare.

One of them can be seen on Sethi I ’s sarcophagus, in an image dedicated to the final part of the ritual “The book of the doors”

The divinity shapes her body into a circle.

Its feet touch its head from behind.

With the hands it bears  the goddess Nut, who stands holding the solar disc on her head.
