The interweaving of knowledge and philosophy up to the modern era goes back to Thales of Miletus, regarded as one of the seven sages of Greek civilization (624 BC – 543 BC). "Know Thyself" is an aphorism of knowledge attributed to the times of Thales. This Greek Maxim etched in stone at the gate leading to the temple of Apollo in Delphi has become a philosophical question studied to this day. Another sage in the exposition of total knowledge, a Vedic master of Indian philosophy, was Adi Shankara (509 – 497 BC); his teachings of Advaita, the Nondual reality of life, provided an in-depth study of knowing the true nature of Self and fulfilling on a practical level to his society what the Greeks knew as the highest teaching. This book explores the Nonduality, Oneness philosophy—modern spiritual teachings from ancient times. My discussions about Oneness have the flavor of the Advaita tradition, a revived and current view from Vedic Science, and the contemporary study and thinking about Nonduality. —Shivada Amrita Website: advaitaspeaks.com
