In Sanatan: The Backbone of Modern Science, I explore a question that has always inspired me-what if the discoveries of modern science were not entirely new, but rediscoveries of ancient wisdom preserved within Sanatan Dharma? Through the journeys of my characters, I attempt to bridge the laboratory and the ashram, showing how vibration, geometry, Ayurveda, cosmology, and Sanskrit reflect principles that science is only now beginning to understand. This book is neither blind faith nor a rejection of modern knowledge; it is a dialogue between physics and philosophy, matter and consciousness. By connecting Vedic insights with contemporary research, I seek to remind readers that science and spirituality are not opposing forces, but complementary paths leading toward the same eternal truth.
