This momentous book `Sacred Stones in Indian Civilization' analyses the primitive secret civilisation of non-Aryan India. It takes the reader on a journey to a very primitive world in the dark antiquity where birth, life and death got expressed in or with stones popularly known today as megaliths. The book brings forth the numerous primitive megaliths discovered by the author. He brings out the forgotten Goddesses, their glory and the uvanished subtle understanding of the sacred lands once spread all over the world including India. The book ventures to correlate megaliths with the erstwhile secret civilisation of India while considering them as major relics and sources of the country's prehistory of which we know so little to boast of. It is from this civilisation we have learnt mathematics and astronomy. The Bodhayana Shila, the Vishwarup Shila-all sacred stones of mathematical and astronomical significance-of this secret civilisation built during hoary antiquity are bound to dumbfound and compel people to rethink about the origin of mathematics, astronomy and of this unknown civilisation. Abundantly illustrated and lucidly written in the travelogue form, this book by unravelling the mysterious past and shattering many myths and preconceived ideas about India's pre-history, is sure to initiate much debate and modify the manner you look into your past. It is the result of over nine years of the author's discovery and research. Moreover, this is essential and interesting reading for those who desire to know the unknown, enigmatic India, her sciences and temples, her age-old less known beliefs.
