Bhishma (Devavrata)

Shantanu wanted to marry Satyavati, but her father demanded that her future son inherit the Kuru throne. The king returned without accepting the condition, and Devavrata noticed that his father had become troubled. He went to Satyavati's father and offered to give up his own claim to the throne. The first obstacle appeared to be removed, but the fisherman still feared that Devavrata's future sons might challenge Satyavati's children.

Devavrata then made a second promise. In Mahabharata: The Greatest Spiritual Epic of All Time, he swore that he would never marry and would father no children. He gave up the possibility of a household as well as the crown. The vow secured the succession for Satyavati's line because there would be no son of Devavrata to make a rival claim.

The promise changed the scene at once. The gods and immortals heard Devavrata speak and were struck by the severity of what he had chosen. They cried out the name Bhishma, a person who had undertaken a difficult vow. The new name marked the act that had taken the prince away from ordinary royal life.

Shantanu could now marry Satyavati, and Devavrata returned to his father without the throne or the prospect of children. His decision answered a private grief in the king, but it also reshaped the future of the Kuru house. The story closes when the gods name him Bhishma. The title belongs to the vow itself, a promise made in public that bound Devavrata's body, inheritance and descendants to the marriage his father wanted.
