Schopenhauer read the Latin translation of the ancient Hindu texts, the "Upanishads", translated by French writer Anquetil du Perron from the Persian translation of Prince Dara Shukoh entitled "Sirre-Akbar" ("The Great Secret"). He was so impressed by philosophy that he called it "the production of the highest human wisdom", and believed it contained superhuman concepts. Schopenhauer considered India as "the land of the most ancient and most pristine wisdom, the place from which Europeans could trace their descent and the tradition by which they had been influenced in so many decisive ways", and regarded the "Upanishads" as "the most profitable and elevating reading which [...] is possible in the world. It has been the solace of my life, and will be the solace of my death."
