Biography of Dhritarashtra

Dhritarashtra’s Blindness:

Dhritarashtra was born blind, and his blindness played a significant role in the Mahabharata’s narrative.
Ambika, Dhritarashtra’s mother, had closed her eyes out of fear during her meeting with the sage Vyasa, resulting in Dhritarashtra’s blindness.

Marriage and Children:

Dhritarashtra married Gandhari, who voluntarily chose to share his blindness by blindfolding herself throughout their married life.
The couple had one hundred sons, collectively known as the Kauravas. Duryodhana was the eldest of the Kauravas and played a central role in the Mahabharata as one of its main antagonists.

Dhritarashtra’s Role in the Mahabharata:

Due to his blindness, Dhritarashtra was not eligible to inherit the throne of Hastinapura. Instead, the throne went to his younger brother, Pandu.
After the death of Pandu, Dhritarashtra became the king and ruled over Hastinapura.
Throughout the Mahabharata, Dhritarashtra struggled with conflicting emotions and loyalties between his sons (the Kauravas) and his nephews (the Pandavas).
His love for his sons, particularly Duryodhana, often led him to make decisions that were not in the best interest of maintaining peace and justice.

Kurukshetra War:

Dhritarashtra’s reluctance to address the growing animosity between the Kauravas and the Pandavas contributed to the eventual Kurukshetra War.
Despite efforts by Krishna and others to avert war, Dhritarashtra was unable to prevent the conflict.

After the War:

The Kurukshetra War resulted in the deaths of many of Dhritarashtra’s sons, including Duryodhana.
After the war, Dhritarashtra renounced the throne in favor of his surviving nephew, Yudhishthira, the eldest of the Pandavas.

Tragic End:

Dhritarashtra, along with Gandhari and Kunti, chose to retire to the forest for a life of penance.
In a tragic turn of events, they perished in a forest fire, symbolizing the end of the Kuru dynasty.
Dhritarashtra’s character serves as a complex and tragic figure in the Mahabharata, and his decisions and actions contribute to the epic’s overarching theme of dharma (righteousness) and the consequences of adharma (unrighteousness).
