Question 3.
Write a note on Saraswati river.
Answer:
According to Rig Veda, Saraswati river is considered Naditame (best in all rivers), amtritame (best in mothers) and Devitame (best in goddesses).
According to Indian archaeology council, it originates from Rupan glacier of Shivalik range of Himalayan ranges which converted into a water current. After reaching ‘Adi Badri’ it received water from Drishadvati and Hiranyavati as tributaries. At present the river which flows between Satluj and Yamuna rivers, is Saraswati. Due to tectonic movements beneath the earth and elevations of earth this river shifted towards west and ultimately become dry of the earth’s surface due to lack of supply of water and slowly become extinct it flows beneath the earth, i.e. in land (Antah Salila).

Research done by ‘Isro’ proves present drainage system, i.e, Brahm Sarovar of Kurukshetra, Pehva semi-circular lakes as well as visible drainage of rivers from Punjab, Haryana and through North-Western Rajasthan to Pakistan in form of Ghaghar Hakra. Nara is the example of presence of so-called Saraswati river which flows under earth by extracting water of this inland flowing extinct river regions present in close proximity could be developed.
Evidence found in early excavations witnessed that Harappa Civilization was named as Indus valley civilization. But on the basis of remains found in 2600 at the bank of vedic Saraswati river, was named Indus-Saraswati Civilization.
