Yaga is related to the Fates (three Greek goddesses of fate), almighty Moerae: Clotho (who spins), Lachesis (who measures off), and Atropos (who cuts off). They are mistresses of fates-threads. Not only men, but also immortal gods are in their power.
Yaga is powerful – she ties and tears.
She weaves, she threads, she designs our life.
