According to Durga Pooja vidhanam there are Nine unique forms of Durga who bless with various boonsand gifts. Details of all the Nine Durga Avatars are as follows,
Jatavedo durga- The Durga who represents fire and especially the fire in which deities are invoked i.e., the fire which resides in Homa Kunda and used in spiritual practices. This Goddess extinguished the fire that emerged from Lord Shiva’s eye to burn Kama (Cupid) who instilled seduction in Shiva’s heart. The fire could never be put down and started destroying Earth. Jatavedo Durga carried this fire and dropped it in River Ganga.
Santhi durga- The only thing sought by Kings, soldiers, ascetics and even animals is, Peace. This Goddess, Shanthi Durga helped Lord Shiva attain peace as He was enraged by an incident which later on lead for the creation of Shakti Peeth (Powerspots of Goddess). Relief from debt, physical and mental ailments are Her boons.
Shoolini durga- She accompanied Lord Sharabheshwara to remove the ignorance of Lord Narasimha. She beholds a powerful Trident (Trishul) hence called Shoolini Durga. She protects her worshippers from negative and evil forces.
Shabari durga- When Lord Shiva took the form of a Hunter, Goddess Shabari Durga takes the form of a Huntress and accompanies Him. She is depicted holding bow and arrow.
