Meanwhile, army of the powerful demon Mahishasura, who could only be killed by a warrior Goddess, had reached heaven to overthrow the Gods from their abode.

That is why She is surrounded by Siddhas, Gandharvas, Yakshas, Demons and Gods who are worshiping her. The Siddhi that she provides is the realization that everything is Supreme Being or Brahman. If a “sadhaka” worships in the prescribed manner with his full faith he acquires all “Siddhis” and nothing remains unattainable from him in the universe.
