Maa Siddhidatri is the ninth and final manifestation of Goddess Durga, and her worship is observed on the ninth day of the Hindu festival of Navratri. The name "Siddhidatri" is derived from two words: "Siddhi," which means "divine power" or "spiritual attainment," and "Datri," which means "giver" or "bestower." She is the ultimate source of supernatural abilities and spiritual accomplishments.

The Navratri story of Maa Siddhidatri signifies her divine power and her role as the granter of spiritual and worldly achievements.
