on the way to the spheres of light
The dark spheres in the hereafter serve for letting go of the dark feelings and then being able to enter the first sphere of light.
Illustration: Divina Commedia, see Dante and Doré.
After the earthly life, a human being with a dark or shadowy life of feeling can end up in a dark or shadowy sphere in the hereafter.
Essentially, he is on the way to the spheres of light.
If he can let go of his dark feelings, he can enter the first sphere of light.
Just under the first sphere of light lies the Land of Twilight.
Below that lies the ‘Land of Hatred and Lust and Violence’.
And in the deep darkeness lies the Valley of Sorrows.
