When Gandhari, the princess of the kingdom Gandhar was engaged to be married to Dritharashtra of Hastinapur, little did she know that her husband was a blind man. She was crushed yet she married him for the sake of her parents and her kingdom. On the day of her marriage she takes a oath to blindfold herself for the rest of her life and give up on the pleasure of sight in order to prove her devotion towards her husband. Gandhari was blessed by Lord Mahadev that she will give birth to one hundred sons in this lifetime. Thus she becomes the mother of the Kauravas.
When Gandhari was engaged to be married to Dritharashtra, her elder brother Shakuni was not very pleased. He was very upset with his father who chose the welfare of his kingdom over the happiness of his daughter. Hence Shakuni decides to destroy the kingdom of Hastinapur inorder to avenge Bhishma Pitamah who brought the proposal to the kingdom of Gandhar and he moves into Hastinapur and religiously devotes himself in fulfilling his sole life goal of destruction of the kuru clan. Thus the Kauravas grew up on the foundation of hatred laid down by their maternal uncle. Shakuni kept feeding the Kauravas the bitter fruit of revenge. At every stage of the lives of the Kauravas, Shakuni was paving the path for Kurukshetra war.
When Shakuni was playing this foul game, what was Gandhari doing? When she blindfolded herself did she decide to turn a blind eye towards the cruelties of her brother? She could've asked her brother to leave Hastinapur for good and I am sure Shakuni would've even done that. But what stopped her from doing it? Was she insecure in her husband's home and felt secured when her brother was around? Was she helpless because she was always submissive to her ever frustrated and dominating husband? Or did she have that desire in her heart to see her eldest son rule the kingdom which was never wholeheartedly given to her husband in the firstplace? or was she also avenging Bhishma Pitamah who was the reason for her marriage into the kuru clan? Gandhari is a very intriguing character of the Mahabharat indeed. Though she proved to be a devoted wife, she wasn't a very good mother. She could have shown path of Dharma to her hundred sons just like Kunti did to her five sons but she decided to stay mum instead. If only she had put her foot down, Mahabharat would not have been what it was. Gandhari was never a bad woman and neither were her intentions evil. So why was she a silent spectator her brother's wickedness and her son's brutality and injustice. I will leave this question open to everyone to ponder on.
