The four main components that form wealth of a nation are Land, labour, capital and organisation. Dr S Kalyanaraman explains the role played by each of these in generation of wealth of Bharat. Indian soil was rich alluvial soil due to Himalayan rivers and rich also in terms of metal ores. The seals from Saravati-Sindhu Civilization from 3 century BC speak a lot about Bharat as a country rich in metal, material, alloys, cotton, silk, herbal products and developed agriculture. Evidence of cultivated land, water resources used productively, water management system by dividing into channels, storage reservoirs, drainage system are visible in Dholavira and other sites. Textile was well developed due to cotton cultivation, spinning, weaving and even dyeing with pigments was developed. The evidence of silk cultivation too has been found.
The Sindhu-Sarasvati Civilization was also known as clothier of the world. The discovery of Tin bronze alloy resulting in to copper made the Neolithic age emerge in to copper age in the 4th Millennium BC. Dr S Kalyanaraman discusses in detail how invention of copper and iron/ steel created tools of agriculture like sickle, weapons and articles of daily use made Bharat a super power in terms of Metallurgy. The artisans were into gem crafting, metal working, pottery, dyeing textile, extraction from juices making the civilization into a highly sophisticated one. The Tin Bronze revolution also helped to develop Maritime routes of 3rd Millennium BC making Bharat a rich civilization.
