What is "mahadevi"

In Hinduism, Mahadevi ( Sanskrit: Mahādevī, Devanagari: महादेवी) or "Great Goddess" is the goddess or devi that is the sum of all other devis – an all-encompassing female deity as the consort or complement to an all-encompassing male deity ( deva) or the Ultimate Reality ( Brahman) in Shaktism.

Mahadevi is the soul of the universe and the universe itself. She is the source of wealth, knowledge, forgiveness, peace, faith, fortitude, fame, modesty and mercy. The purans mention her as Nirguna Maheshwari Devi Mahamaya, meaning "the absolute truth", Shiva's consort, and mother of all. Along with Nirguna form Mahadevi is also mentioned as Sarguna (attributes) and Vagdevi (speech).
