Siddhidatri Ji

Siddhidatri, "giver of perfection," is the ninth and final of the Navadurga, goddess of siddhi (spiritual attainment), representing the goddess's own arrival at her highest, supreme form as Mahashakti.

Her name joins siddhi (spiritual attainment, perfection) and datri (giver, bestower). Her name is also commonly rendered Siddhidhatri.

She is shown with four arms holding a chakra (discus), a shankha (conch shell), a mace, and a lotus, seated on a fully bloomed lotus or, in some depictions, a lion. Some images show her flanked by gandharvas, yakshas, siddhas, asuras and devas, all paying her homage.

According to the legend recorded of her, at the dawn of creation Shiva worshipped the unmanifest form of the great goddess Mahadevi in order to perform the act of creation. The goddess is said to have emerged from the left half of Shiva's own body as Siddhidhatri, and to have then conferred upon him the ashta siddhi, the eight classical spiritual attainments. Because of this origin from Shiva's left side, she is closely associated with the composite Ardhanarishvara form, in which the left half represents Parvati.

Consort Shiva, in the particular sense, in this legend, of having emerged from him rather than simply having married him.

Worshipped on Navami, Navratri's ninth and final night, marking the completion of the goddess's nine-stage unfolding into her supreme Mahashakti form. Separately, the Agni Purana lists an alternative set of nine names it also calls "Navadurgas" (Rudrachanda, Prachanda, Chandogra, Chandanayika, Chanda, Chandavati, Chandarupa, Atichandika, Ugrachanda), a distinct textual tradition worth noting rather than a contradiction of the nine forms described here.

No single named pilgrimage site stands out for her in the sources consulted; her worship follows the general Navami-night pattern that closes Navratri across regions.
