The story of Goddess Durga is an allegorical representation of the continual conflict,
Rraging within every human between divine and demonic instincts.
Mortals have to fight a gruesome battle against the negative passions like anger,greed,jealousy.
It is the awakening of divine power that can free a person from the bondage of ego to attain supreme bliss.
Navarathri is symbolic explanation of the story of Goddess Durga in a convincing manner.
Navarathra-these 9 nights are divided and devoted to the Trinity of God,worshipped in female form-
3 nights for Mahal Kali or Durga ,3 nights for Maha Laxmi and 3 nights for Maha Saraswathi.
Durga or Maha Kali represents Tamas or demonic traits,so she is black in colour.
Maha Laxmi represents Rajas or desire so she is red in colour.
Maha Saraswathi represents Satwa or enlightenment,so she is whole white in colour.
Durga or Maha Kali is Goddess of war.She is called Raja Rajeshwari because she is worshiped by kings and emperors.
In North India she is worshiped as Maheshwari.In West India she is worshiped as Maha Laxmi.
In East India she is worshiped as Maha Kali and in South India she is worshiped as Maha Saraswathi.
India which is protected by these 4 forces is really a land of devotion and divine energy.
Rigveda says, the universe is completely pervaded and protected by the force which is identified and worshiped as Mother Durga.
