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
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
