Jagad Yoni

Jagad Yoni (devanāgarī: जगद्योनि, from jagat, "world" and yoni, "womb") is a Sanskrit term usually translated as the "womb of the world." According to H. P. Blavatsky, however, the jagad-yoni "is scarcely so much 'the Mother of the World' or 'the Womb of the World' as the 'Material Cause of the Universe'." She also related it to the Gnostic concept of Pleroma:

The Plêrôma or Plenum must be distinguished from Mûlaprakriti. The Plerôma is infinite manifestation in manifestation, the Jagad Yoni or Golden Egg: Mûlaprakriti is an abstraction, the Root of the Jagad Yoni, the Womb of the Universe, or the Egg of Brahmâ.
