Sree Narayana Guru (1855-1928) was a spiritual leader and social reformer who led powerful movements to promote social equality. Not Many, But One brings together his work in two rich volumes of translation and interpretation, pieced together for a modern readership. In Volume 2, we see how Sree Narayana Guru revived the Advaita philosophy. The book also focuses on the correlation between the teachings of Advaita, the conclusions of modern physics and cosmology, and how Advaita reveals the complex secrets of the universe. It explains the theoretical, observational and experimental findings given by science about the origin, evolution, existence and future of our universe. Volume 2 also explores the Big Bang theory, the inflation theory, the role of dark matter and dark energy, the concept of space and time, the anthropic principle, supersymmetry, spontaneous symmetry breaking, string theory and other latest avenues of modern science. The translations, explanations and commentary given are simple and conceivable by ordinary readers who may not be well equipped with the complexities of intuitional spiritual findings of Advaita and hypothetic conclusions of quantum physics-but without compromising on the authenticity of the works. Vedic philosophers, physicists, cosmologists and enthusiasts who love science and spirituality will appreciate this enterprising effort - though with limitations - in bringing closer the two hitherto uncompromising schools of thought. The devotees of Sree Narayana Gurudev will find an opportunity to go deeper into his works.
