Caste: the new civil conflict in India
The Aryans left behind a rich oral tradition, in which sacred texts were committed to memory and passed down from generation to generation.Considering the time elapsed since these texts, in the form of hymns or "Shlokas" (couplets) were composed, there is a remarkably little difference between different versions extant in the various corners of India.
The Rig Veda, widely held to be one of the earliest of the texts, speaks of the "Sapta Sindhu", the seven great rivers which formed the backbone of civilization at the time.I give below the Vedic names together with the corresponding modern names:
Vedic Modern
Sindhu Indus
Vitasta Jhelum
Asikini or Chandrabhaga Chenab
Parushini or Iravati Ravi
Vipasa Beas
Shatadru Sutlej
Saraswati ?
Of the rivers mentioned in the Rig Veda, Saraswati was held to be the mightiest: yet it seems to have disappeared, while all the others survive.
Modern geographical evidence, together with the data collected from remote satellites, suggest the following turbulent history:
As late as only ten thousand years ago, the glaciers in the Himalayas started thawing, releasing great amounts of water, the major part of which flowed across the Indian sub-continent into the sea.The Indus, Jhelum, Chenab, Ravi and Beas formed one such river valley, the Sutlej, Saraswati, Drishadvati and the Yamuna formed another, with the Ganges and its tributaries forming a third. Flush with copious fresh water, fertile plains grew up around these rivers, and the Saraswati and the Indus systems formed the basis for the flourishing Harappan civilization.
Geological upheavals continued in this historically ancient but geographically young area. Tectonic upheavals in the Himalayas some 4000 years ago. cut off the glacial supply of water to the Saraswati: upheavals downstream caused the Sutlej to break away, changing its course to meet the Beas in the west, and the Yamuna to flow to the Ganges to the East. The Saraswati, now called the Ghaggar is now a rain-fed river, surviving around 300 miles before emptying itself into the Thar desert.Along with the river, the civilization that grew up around it also disappeared.
