Jagatdhatri or Jagaddhatri or Mahadurga (Bengali pronunciation: [d͡ʒɔɡod̪ʱːat̪ɾi] ^ⓘ, lit. 'Bearer of the World') is an aspect of the Hindu goddess Durga, worshipped in the Indian state of West Bengal and other states like Odisha and Jharkhand. Maa Jagadhatri, the Goddess who is revered as the protector of the world. In Bengal, her puja is celebrated as the comeback of Devi, specifically in Krishnanagar, Chandannagar, Santipur, Rishra, Midnapore,Singur and Guptipara.

The legend of Jagaddhatri is inspired from a tale in the Kena Upanishad. In the Katyayani Tantra, the following legend is told. After the goddess Durga killed Mahishasura, the gods of Svarga forgot about her powers. So, in order to test them, Parvati appeared before the gods Agni, Vayu, Varuna, and Chandra, who considered themselves invincible and were engulfed by ahamkara (ego). She asked them to move a tiny blade of grass. Vayu failed to pluck it; Agni failed to burn it. Every god failed at the task. In the end, they understood that the Goddess is the source of all power in the universe; even theirs. The goddess appeared before them as Uma, riding on a lion. The goddess is equated with Brahman in the narrative. The goddess gave the ego of the gods the form of an elephant. Jagaddhatri is depicted sitting on a lion with an elephant under them. The elephant, symbolizing ahamkara, lies under the paws of her vahana the lion, who symbolises courage, valour and the strength to overcome any challenges, including one's internal struggles with the Shada Ripus ("the six enemies"). She is named as Mahadurga in Shiva Purana. While in some other texts, as Uma Haimavati.

Her dhyana mantra describes her weapons, vahana and her iconography. She is sitting atop a lion, wearing different jewelry, in her four hands Devi holds bow, arrow, chakra and Samkha. She is reddish like the rising sun and she is wearing a snake garland. Her reddish colour and weapons are the symbols of raja guna but this is not for destruction and going to war. Rather this is to keep the world focused on Ritam & Satyam.

In her stotram (Jagadhatri Strotram), she has been invoked as Adhara bhutah, Dhritirupah, Dhurandharah, Dhruvapadah, Shaktistah, Shaktirupah, Shaktacharpriyah, Shaktivigrahe. "You must believe in the Ishwara rupa. Do you know the meaning of Jagadhatri rupa? She is carrying the world. If she stops then the world will get destroyed" is said by Sri Ramakrishna.

She sustains the universe through her Yoga shakti. Naga/Sarpa is the symbol of Yoga & Upavitam is the symbol of Bramhin. Devi is yogini. She is using the world through her maha yoga shakti. The act of rescuing the world is her lila.

It is said that she had killed the elephant demon, Karindrasura. Its mention is not found in her dhyana mantra but in her idol an elephant is seen below her mount lion, who is none other than Karindrasura. It's said that once the Airavata of Indra was cursed and therefore it took birth as Karindrasura. He became a very strong demon. Once, he saw goddess Ganga and was attracted to her beauty. Hence, he lusted for her, but Ganga rejected his proposal. Karindrasur became very furious about the rejection and forced Ganga to come with her. To save her life she prayed to goddess Mahamaya and she appeared in the form of Jagatdhatri. A vicious battle took place between the goddess and the demon, where Goddess Jagatdhatri slayed Karindrasura with the help of her chakra, Bow and arrow. From then she was known as Karindrasurnishudini. After that Airavat was free from the curse.

Another encounter mentions that Karindrasura became an important and powerful official of Durgamasura whom Goddess Durga killed by taking form of Jagaddhatri during the battle of Durga and Durgamasura.

Another story tells that when Mahishasura took form of an elephant during the battle with Goddess Katyayini, he came to be known as Karindrasura, who was slayed by Goddess in form of Jagddhatri with Chakra, bow and arrow. In this encounter Mahishasura and Karindrasura are indifferent, just with different animal forms.
