In the Manu Smriti, the Drishadwati and the Sarasvati define the boundaries of the Vedic state of Brahmavarta: It says that the land, created by the Gods, which lies between the two divine rivers Sarasvati and Drishadvati, the (sages) call Brahmavarta. The text also says that although the Sarasvati formed the northern boundary of Kuru Pradesh, the Drishadwati flowed in south of Kuru Pradesh and north of Brahmavarta. According to the Mahabharata, the southern boundary of Kuru Pradesh was Guru Drona's ashram (present-day Gurgaon at one end and Rohtak and Jhajjar at the other); therefore, the Drishadwati flowed in the southern portions of these cities. Although about 100 streams flowed south to north in the -wide Aravalli Range during the Vedic period, the only large river is the present-day Sahibi. The Sahibi has a lower flow at present because of low rainfall in its catchment area and has a wide, dry bed which carries water from the districts of Jaipur, Sikar, Alwar Rewari, Jhajjar, Rohtak and Delhi in Yamuna.
