“Divine Mother,” “Universal Mother,” and “Cosmic Virgin” are alternate terms for the feminine polarity of the Godhead, the manifestation of God as Mother, Omega.
Matter is the feminine polarity of Spirit, and the term is used interchangeably with Mater (Latin, meaning “mother”). In this context, the entire material cosmos becomes the womb of creation into which Spirit projects the energies of Life. Matter, then, is the womb of the Cosmic Virgin, who, as the other half of the Divine Whole, also exists in Spirit as the spiritual polarity of God.
Jesus himself recognized Alpha and Omega as the highest representatives of the Father-Mother God and often referred to Alpha as Father and to Omega as Mother. Those who assume the feminine polarity of consciousness after the ascension are known as Ascended Lady Masters. Together with all feminine (femininely polarized) beings in the octaves of light, they focus the flame of the Divine Mother on behalf of the evolutions of mankind evolving in many systems of worlds. However, being androgynous, all of the heavenly host focus any of the masculine or feminine attributes of the Godhead at will, for they have entered the spheres of the Divine Wholeness.
