There was a great leap of development in the Post-Shiva era between 7000 and 3500 years ago. The world population grew from 5 million to 40 million in this period. Over 70% of the world population was (and still is) in Asian/China/India
A full-fledged civilization, with the four symbols of advancement – agriculture, the wheel, dress and script was thriving. Human beings had grasped the rudimentals of these inventions and developed them. They moved from the Neolithic period of agriculture to the Bronze Age and Iron Age by developing the use of copper, iron and eventually steel. Cities were built, boats sailed the oceans, pictorial letters developed in Mesopotamia, China, Egypt and India. Civilization moved from mountain hills down to the banks of rivers. Where rivers met people mingled, learnt from each other and enriched their culture.
In Rarh, the oldest land in India which was inhabited since the dawn of human beings 1 million years ago, the people who were responsible for discoveries like the wheel or bullock carts were known as “Mahatmans.” <<The title “Máháto” came from Mahatman. The Máháto community of today are the descendants of the talented people of the past. Some people think that Mahato is a caste, but this is not correct.>>
<< That community which first learned the use of iron leapt over the boundary of the stone age, bone age and bronze age, and was considered to have the most advanced civilization. The use of iron brought a new unfolding to the movement of human history, a new radiance. At that time the wheel had not yet been invented, and thus there were no vehicles. Later, with the help of iron, human beings produced the wheel. They learned to wage war seated in vehicles mounted on wheels. By sharpening the edge of the wheel they invented a weapon called the discus. The boomerang is also a type of discus used by the Maoris of Australia. In India and Central Asia people learned the use of the wheel in very ancient times, but no matter how long ago they learned it, they learned it after they learned the use of iron. That is, first they invented the chariot wheel, then afterwards turned the wheel into a weapon.>>
<<That invention also marked a new victory. Human beings had created something new, effecting a greater acceleration in human progress. All this took place in the physical sphere. To keep pace with these changes there were corresponding changes in the human physical structure. The cranium became larger, the skull became smaller, the arms became shorter, the body hair decreased and the jaws became more elevated. In the different parts of the world these changes took place in different ways. In some parts the jaw became more elevated, in other places it dropped. In some parts human complexion was brown, in some parts white and in other parts reddish. These physical changes occurred in adjustment with the changes in the psychic world. This is how human beings advanced.>>
