Rarh
In SHABDA CAYANIKÁ PART 2, DISCOURSE 8 (IIGAL TO IIKS'AN'AKA/ IIKS'AN'IKA/ IIKS'ANIKA') it says:
"I had gone to Ranchi for a few days in relation to an idea I had that the civilization of the Koyel River-valley found in the west of Ranchi District was a branch of the Rarhi civilization of central Gondwanaland. To the east of Ranchi was the Suvarnarekha River-valley, which in terms of language, culture and heritage belonged to Rarh. Each day I would go to one or two different spots in the Suvarnarekha River-valley in search of archaeological artifacts of ancient Rarh."
"All day long I travelled like a whirlwind from village to village in Ranchi District's Silli area and the Jhalda and Jaipur areas of what was at that time Manbhum District, just adjacent to it. This region is also worthy of being recognised by archaeologists as the cradle of Rarhi civilization. Here the Suvarnarekha River-valley, Kamsavati River-valley and Damodar River-valley (Alkushi, Kupai, Uttara' or Chot'ki Guyai and Daks'in'a' or Bar'ki Guyai) are all close to each other and I was able to discover many things there."
"The far western fringe of Rarh, where the Suvarnarekha, Kansavati and Damodar River-valleys come together, we can call the cradle of both Rarhi and human civilization."
"I was quite pleased with the prospect of presenting the land of Rarh in a new way to people. And I was especially pleased, looking at the straightforward faces of these dark-complexioned, Austrico-Scythian-Negroid people of Rarh, to think that, though they are neglected today, at one time they were perched at the summit of civilization. They were the forefathers of human civilization and the trumpets of Bengali civilization."
"Rarh was not only the starting point of civilization, Rarh represented the first ever steps towards cutural progress. The intermingling of the basins of small and big rivers and the exchange of activities and ideas, laid the foundation for the civilization and the culture of Rarh, whose splendour in turn ushered in a golden dawn not only in Rarh, but also in the life of all of the underdeveloped humanity of that dark age."
"Human beings originated at a few particular points in this planet. Even without getting into a detailed discussion as to which humans appeared first and which appeared later, I can say that origin of humankind in Rarh is very ancient. No trace can be found of any more ancient human habitation."
