Satyavati was a fisherwoman who used to drive a boat. One day the sage Parashara was in a hurry to attend a yaga. Satyavati helped him cross the river borders. On this account, the sage offered her a mantra which would result in begetting a son who would be a sage with wisdom and all good qualities. Satyavati immediately recited the mantra, and thus Vyasa was born. She kept this incident a secret, not telling even King Shantanu.
