The story of Kalima begins with Lord Shiva telling Parvati Mata (One of the forms of Durga)

The story of Kalima begins with Lord Shiva telling Parvati Mata (One of the forms of Durga) that he needs to go and meditate. Soon after Lord Shiva leaves, the King of the Rakshasa arrives asking for the blessings of Lord Shiva and Mata Parvati. The Rakshasa are very devoted followers of Lord Shiva so she tells him that Lord Shiva is meditating however, he can have her blessings as long as he does not break any of the rules of war. With that, the Rakshasa left. The Rakshasa attack and reach the gates of Heaven and have been defeated all the way to there. Fearing complete defeat, they rush to find Lord Shiva. When they find Mother Parvati, she tells them that he is meditating. 

They ask for her blessings, she says that she cannot offer it because the Rakshasa King already has it. They finally ask, "Can you lead or army?" Parvati agrees with the condition that they obey her every order. The Devas agree to her terms. As the war continued just outside of Heaven, Parvati took the form of Matha Durga and lead the army of Devas. The Devas army had been devastated by the battles with the Rakshasa. Now, with Durgama leading the battle, the Rakshasa advance was stopped. As the battle continued, Durgama's leadership gave the advantage to the Devas and the Rakshasa started to lose. 

The King of the Rakshasa grew nervous. The Devas were joyous. As the battle continued, the Rakshasa lost ground. Then, all at once, the Rakshasa retreated. The Devas started to pursue the retreating Rakshasa. Durgama ordered the Devas to return to their positions and not pursue the Rakshasa. The Devas ignored her. Even the leaders of the Devas took off after the retreating Rakshasa army. They left Durgama alone with only her personal guards. From behind, a small group of the Rakshasa lead by the Rakshasa King surrounded Drugama. The King spoke. "Mata, I cannot attack you and I cannot have you leading the Devas. By the rules of combat, you should surrender however, you may also leave the battle field or even ask me to surrender. I will do as you say." Durgama smiled. "You have done what is your duty and I have taken leadership of the Devas. As such, it is my duty to surrender. As long as you follow the rules of combat treat your prisoners well, I will not fight or seek escape while in prison." The Rakshasa King agreed. Once Durgama agreed to be a prisoner, she returned to her form as Parvathi and went to the Rakshasa prision.

 Once Parvathi was in prison, the Rakshasa army stopped its retreat and attacked the Devas. The retreat had been a trick to get the Devas away from Durgama. The Devas were caught off gaurd. They retreated to their original positions and searched for Durgama. They found their leader missing and realized their mistake. As the Rakshasa advanced, most of the Devas were either captured or killed however, a very few escaped. The Rakshasa army advanced to the gates of Heaven and defeated the army guarding them. The Rakshasa army took control of Heaven and the Rakshasa King seized the throne making all of the Devas that remained into servants. After enjoying his victory, the Rakshasa King decided to leave Heaven and bring its riches to his own people so they could enjoy the celebrations. He left explicit orders to find the remaining Devas that had escaped capture and above all, to treat the prisoners well until the victory was complete. With that, he left.
