Hecate

Hecate, Dark Goddess, Bright Star of the Holy Nights

‘When the light of the outer sun is faintest and its warmth feeblest, now is the time when the soul withdraws into the darkness but can find within itself the inner, spiritual Light that is kindled in the other darkness.

But for one whose eyes of spirit are opened the Thirteen Days and Thirteen Nights between the 25th of December and the 6th of January are a time of deep spiritual experience’.
Rudolf Steiner about the Holy Nights.
