It has been observed in the previous book titled 'Origin of Hindu ? The Name', that the dictum of going, moving forward, became the central tenet of a huge number of human beings, who essentially were the residents of India. Those people were termed as Hindu. Even when the root of this concept is logically proven, then also a question crops up and remains unanswered. Why the act of going, moving forward, became so important that a large number of people needed to accept it as the guiding principle of their lives? No tangible evidence has been found of any coercive actions from the part of the propagators of this way of life, not even in the folklores or in the legends. The adherence in all probability was voluntary and self-imposed. For this happening, two broad categories of influences may be credited to: physical and/or cerebral. Physical environment of the land in reference was set by the actions and interactions of the geological forces. Cerebral input must have come from some knowledge base. Structured and recorded knowledge base that is unique to India is found in the Vedas and its annotations. The period by when the geological timeline shows that this land was becoming ready for human inhabitation that was the time around which the trace of oldest literatures of this land may be found. A little later, out of nowhere the world came to know about the existence of a human settlement that was more splendorous than anything known to the Greeks, the best ones in the known world up to that time. This book finds the relationship between the geological formation of the Ganga Plain and the propagation of a new way of life that would be known as 'Hindu' religion in later time. It has been established that the word 'Arya' is a Sanskrit word that means 'the son of the Rishi' and no large human movement that may be termed as invasion, migration etc. needed to be introduced to explain what have happened in this land during that time period.
