Durgam, the king of the demons once asked his minister, "why is it that the gods are always able to win over us? They must have secret powers."

He replied, "The gods have the knowledge of Vedas which gives them great powers."

Durgam decided to get the Vedas and performed a long Tapasya. When Brahma appeared, he requested him to make him the protector of the Vedas. But instead of protecting them, he took and hid them in patal-lok (netherworld).

The yajnas performed with the help of the Vedas used to help the gods and sages became old and weak. On earth, drought and famine occurred because no yajnas were performed to cause rain. There was death and destruction everywhere. Terrified, the gods went to Vishnu for help. He asked them to worship Jagatmata Ma Bhagwati gave them a leaf, it rained on earth and prosperity was restored. Then Ma Bhagwati formed ten goddesses - Kali, Tara, Chinnamastaka, Shrividya, Bhubaneswari, Bhairavi, Bagula, Dhrumra, Tripura, and Matangi from her body. With these goddesses she attacked Durgam and defeated him. The Vedas were restored to the gods and sages.
