Before her wedding ceremony could commence, Amba told Bhishma that she had fallen in love with the King of Salva, and was not ready to marry anyone else. Hearing this from her, Bhishma sent Amba with grandeur to her desired husband. However, Salva rejected her, stating that as Bhishma had bested him at the svayamvara, he regarded him to be her rightful husband. Amba returned to Bhishma and demanded that he marry her according to Kshatriya dharma, but Bhishma declined, due to his vow of celibacy. Lamenting her misfortune, the princess decided to retire to the forest and practise austerities for the remainder of her life. As she wandered, she came across an ashrama, and informed the sages within of her plight. One of the sages happened to be maternal grandfather, Hotravahana, who sympathised with her state of mind, and told her that Parashurama, Bhishma's martial guru, would come to her aid. Parashurama visited Hastinapura, and commanded his disciple to marry Amba. Bhishma refused to obey him, once again citing his vow. Furious, Parashurama engaged in a terrible duel against Bhishma on the field of Kurukshetra for twenty-three days, employing astras, but was unable to best him. He regretfully informed Amba of his failure to change his mind. The princess spent twelve years engaged in severe austerities, which scorched the heavens themselves. Shiva appeared to grant her a boon of her choice, and she solicited the death of Bhishma. Shiva told Amba that she would be born as a girl who would later become a man in her next life, and become a maharathi who would slay Bhishma in battle. Overjoyed, the princess lit a funeral pyre, prayed for the death of Bhishma, and self-immolated.
