SatyavatÄ« was actually the daughter of Uparicara Vasu by the womb of a fisherwoman known as MatsyagarbhÄ. Later, SatyavatÄ« was raised by a fisherman.
The fight between ParaÅ›urÄma and Bhīṣmadeva concerns three daughters of KÄśīrÄja — AmbikÄ, AmbÄlikÄ and AmbÄ â€” who were forcibly abducted by Bhīṣmadeva, acting on behalf of his brother VicitravÄ«rya. AmbÄ thought that Bhīṣmadeva would marry her and became attached to him, but Bhīṣmadeva refused to marry her, for he had taken the vow of brahmacarya. AmbÄ therefore approached Bhīṣmadeva’s military spiritual master, ParaÅ›urÄma, who instructed Bhīṣma to marry her. Bhīṣmadeva refused, and therefore ParaÅ›urÄma fought with him to force him to accept the marriage. But ParaÅ›urÄma was defeated, and he was pleased with Bhīṣma.
