Indian Rivers-holy river Saraswati.

River Saraswati.

Water ascends towards the sky in vapors; 
from the heaven it descends in rain, 
from the rains are born the plants, 
from the plants, are the animals and humans.

The Saraswati river is referred in the RigVeda more than 60 times. It is one of the seven sacred rivers Sapt Sindhu. Until recently, scholars considered the river to be mythical.

The river, which had originated from Kapil tirth in the Himalayas in the west of Kailash, was flowing southward to Mansarovar and then taking a turn towards west.  Thereafter Saraswati travels from the south of Mana pass to meet with river Alaknanda, 2 miles away in the south of Mana village. Descending through Adibadri, Bhavanipur and Balchapur in the foothills to the plains, the river took roughly a southwesterly course, passing through the plains of Punjab, Haryana, Rajasthan, Gujarat and finally it is believed to have debouched into the ancient Arabian Sea at the Great Rann of Kutch. In this long journey, the Saraswati is believed to have had three tributaries, Shatadru (Sutlej) originating from Mount Kailas, Drishadvati from Siwalik Hills and the old Yamuna. They flowed together along a channel, presently known as the Ghaggar River, which is known as Hakra River in Rajasthan and Nara in Sindh.

The Saraswati  passed the Himalayan glaciers in Har-ki-dun in Uttaranchal and emerged at Adi Badri, 30 km. north of Jagadhri, through the foothills of the Shiwalik ranges. The river at its peak was between 5 to 7 miles wide at its widest point and traversed a distance of over 1000 miles through Himachal Pradesh, Haryana, Punjab, Rajasthan to reach Sindhu Sagara,  the Arabian Sea flowing  through Patan and Kutch and meeting the Arabian sea.

Then, between 6000 BC and 4000 BC, tectonic changes caused river-migration and the desiccation of the river. It was completely dry by approximately 2000 BC.

The river had its origin at least as early as 12000 years BC.

Considering that the Rig-Veda mentions the river so frequently, it stands that the river must have been in its peak years. This implies that the Rig Veda must have been conceived in its present form between 12000 BC and 6000 BC.
