Schopenhauer was the first major Western philosopher with a deep interest in Asian philosophies and religions. His favorite book was a Latin version of the Indian Upanishads-the Oupnek'hat-that he used to call the consolation of his life and death. Urs App explains in this book for the first time why Schopenhauer regarded this work as the most excellent in the world, how it is connected with the birth of his philosophy, and what caused him to list it even ahead of Plato and Kant as his major inspiration. This groundbreaking new introduction to Schopenhauer's thought and its genesis explains the role of Indian, Persian (Sufi), Neoplatonic, and mystical ideas as well as meditative states ("better consciousness"). But its focus lies firmly on the central dynamic at the heart of Schopenhauer's entire work: the inner compass that gave it its overall direction.
