Durga puja history

Maa Durga has 10 hands. Durga maata is associated with Shastras. Durga is also called Shakti (Power) created by God to destory bad forces.
Durga maata story is similar to diwali history in which Lord Rama destroy Ravana. There is similar hisory about Durga puja - there was a Buffalo demon - Mahisasur.  God Brahama gave blessing to Mahisasur that he will be invincible and never be killes. Mahisasur took advantage of this and started killing people and he had desire to kill Lord too.  Then god created a maiden Durga to kill Mahisasur.
