Goddess Durga is said to be one of the most powerful deities in the Hindu religion. She is also known by the name of Devi or Shakti which in Hindi means ‘woman’ and ‘power’ respectively. The word Durga in Sanskrit means ‘a fort’ which symbolizes the fact that Goddess Durga is the epitome of strength and womanhood. Other times Goddess Durga is referred to as Durgati Nashini which translates to ‘one who eliminates suffering’. This all sums up to say that Goddess Durga blesses her worshippers with strength, patience and many such virtues, but she even destroys the things that need to be destroyed.
She treats her worshippers just like a mother treats her children. She loves in a most caring way and she is equally likely to get angry when required.
One of the best ways to appease her is by chanting her mantras. The following mantras are extremely powerful and they can transform your life.

 Om jataa jut samaayuktamardhendu krit lakshnam
Lochanyatra sanyuktam padmendu sadya shan naam
It is recommended that Durga Pooja be started with this mantra. It helps in maintaining focus and concentration and every one can chant this mantra.
 Sarva Mangala Mangalye Sive Sarvartha Sadhike
Saranye Trayambike Gauri Narayani Namostute

This is another very important Durga Mantra. It is chanted during almost all the Durga Poojas. This mantra is in praise of Goddess Durga. It says that Goddess Durga is the most auspicious one and she bestows upon the world her blessings. She is the mother of three worlds and protects us all.
