History of the later Harappans and Shilpakara movement - Viyogi, Naval (Kalpaz Publications, 2010)
"The author has proved that ethnically Harappan people were Dravidians, Australoids and Alpines and not Aryans. They were highly civilized, their heritage and culture very rich. They were efficient artisans, great producers and courageous traders. The book says Aryans, a white race of Central Asia, reached North West India in 1700 BC. They destroyed Harappans towns, who had fled to east. The book gives information about denominational Harappan tribes who have settled in various regions of north India including Kumaon Hills." – Publisher's description.
