Mahādevī

In the Shakta scriptures summarized in the provided sources, Mahādevī exists as the primal reality prior to creation (for example, Tripura Rahasya's portrayal of Tripura Sundari) and is identified as the source from which the universe and the Trimurti proceed. Shaiva Purana material summarized in the sources presents a related account in which Adi Parashakti incarnates as Parama Prakriti from Shiva's left half; other Puranic and Upanishadic passages describe her as manifesting the pantheon and residing in the supreme abode Manidvipa (Devi Bhagavata Purana).

Sources present Mahādevī in two complementary modes: as the unmanifest, attribute‑less absolute (nirguna) and as richly symbolic manifest forms (saguna) described in Puranic passages such as the Devi Gita/Devi Bhagavata Purana, Devi Mahatmya, and Lalita Sahasranama. In the Devi Gita episode she displays a cosmic body—e.g., Satyaloka in her forehead, the created universe as her hair, sun and moon as her eyes, the Vedas as her words—while other Puranic texts provide diverse iconographic depictions associated with specific forms like Tripura Sundari, Durga, Kushmanda and Bhuvaneshvari.

The sources attribute to Mahādevī cosmic functions: she creates, sustains, and destroys the universe; she is the life force and supreme knowledge and the source of other gods and goddesses. Epithets recorded in the summaries (Raksasaghni, Samharini, Kalaratri, Bhairavi, Nistha) indicate both nurturing and martial/destructive aspects, and scriptural episodes portray her revealing divine teaching (the Devi Gita to King Himalaya) and being the object of prolonged meditative devotion (Shiva's use of the bīja mantra hrīm).
