The Goddess Jagaddhatri is the form of the Mahadevi that supports the World. Jagaddhatri is formed from the two Sanskrit roots - Jagad is the physical world, and dhatri is support. In modern day Hinduism, Jagaddhatri Devi is considered a name and form of the Goddess Durga.

The formal difference between Durga and Jagaddhatri occurs in Mayatantra and Jagaddhatri is mentioned with reference to Durga in Krishnananda's Tantrasaar. The special puja of the goddess on the ninth lunar day of the light fortnight in the month of Kartick has been referred in Krityatattarnab by Srinath Acharyachudamoni of the 15th-16th century.

Pauranik lore

As per ancient Pauranik lore of the Hindu scriptures, soon after the victory over Mahishasur the Devatas became highly egoistic. They thought because of lending to Durga their instruments the mighty asuras were vanquished. To make them understand that the primordial power is alone behind every action, the Brahman appeared before the Devatas in the form of effulgent Yaksha.

Bewildered by its presence one by one the Devatas approached Yaksha. First the god of wind Vayu. The Yaksha asked him

And it dawned on them that their powers are in reality not their own but derived from the supreme power who as protecting mother holds the entire creation and therefore called Jagaddhatri. Anybody who worships Jagaddhatri becomes absolutely egoless and a true servant of the world which is nothing but a manifestation of the Brahman.
