Parashara was a renowned Author and a Maharishi because of his immense knowledge. Once while crossing the river Yamuna, he came across a beautiful maiden, Satyavati who was also known as Matsya-Gandha (the one who smells like fish) was the daughter of the King of Chedi Kingdom, Uparicara Vasu, but the girl was raised as Kali (the one with dark complexion) by the fishermen chief, Dasharaja. Parashara was smitten by her beauty and wanted a heir from her but she told him that she stank, so he used his powers and transformed her from smelling like a fish to smelling like musk. She was given the name Kasturi Gandha and Yojana-Gandha because her smell could be smelled across a yojana (3.5 to 15kms). Later, She asked for a boon that the child should be knowledgeable and should be known as one of the great sages, and a male child was born, who was named as Krishna Dvaipayana(Krishna- dark complexion, Dvaipayana-born on an island).
Krishna Dvaipayana was also known as Veda Vyasa, because he classified and organised the vedas- Rigveda, Samaveda, Yajurveda, and Atharvaveda. Veda vyasa with the help of Lord Ganesha, the son of Parvathi and Shiva wrote the epic Mahabharata.
