SHAKAMBHARI POORNIMA (शाकंभरी पूर्णिमा):

It is the asspicious day when adi Shakti appeared in the form of Shakambhari (शाकंभरी) and also Shatakhi (शताक्षी) on the day of aashada poornima (ಆಷಾಡ ಪೌರ್ರ್ನಮಿ).

The story of Shakambari is told in Chapter 28 of the Devi Bhagavatam(देवी भगवत), titled, "the glory of Shatakshi Devi', Also in The Devi Mahatmyam (ದೇವಿ ಮಹತ್ಯಂ), her story is told in Chapter 11.

Story according to Devi Bhagvat :

The Dmon Durgam had acquired all four books of total knowledge (The Veda) from Lord Brahma through penance. He also received a boon from Lord Brahma that caused all the pujas, yajnas and havis that were offered to the gods to reach him instead, making him invincible. Durgam became very arrogant and started tormenting the whole world. As a consequence, it did not rain for one hundred years and the whole world was hit by a very severe drought.
The rishis and munis took refuge in the caves of the Himalayas, and meditated upon Adi shakti., The Goddess appeared in front of them. She had countless eyes that gave her the name Satakshi(शत+अक्षी=शताक्षी [अन गिनत आन्खो वाली]), and was carrying grain, cereals, vegetables, greens, fruits and other herbs and because of this was called Shakambari(शक+आम्भरि=शाकंभरी[शकोन को धरण कर के अयि हुयि]). The goddess was so moved by their plight that tears rolled down from her eyes for nine continuous days and nights. The tears became a river, which ended the drought.

 The rishis and munis and the gods then requested that she recover the Vedas, which were in possession of Durgam. Durgam discovered through his messengers that people were living happily and immediately attacked with a large army.
The goddess protected the frail rishis, munis, gods and others by putting up a huge wall of fire around them, and then let her discus hover around it. There ensued a tremendous battle between the Devi and Durgam. From her body manifested the ten most powerful powers who had never been in the universe before Dasha Mahaavidyas and 64,000 other goddesses. At last the goddess Satakshi/Shakambari killed Durgam with her trident and recovered the Vedas from his possession. At that very moment all the mantras and japas that the rishis, munis and gods had performed earlier but had been absorbed by the demon Durgam transformed into the bright light of a 10,000 suns and entered the Devi. She then handed over the Vedas to the deities. Adi Shakti is also knowns as Durga because she killed the demon Durgam.
