उपनिषद्- The Upanishads: Selection from the 108 Upanishads Text with English Tra
"The Upanishads are the sources of the Vedanta philosophy, a system in which human speculation seems to me to have reached its very acme". "I spend my happiest hours in reading Vedantic books. They are to me like the light of the morning, like the pure air of the mountains, so simple, so true, if once understood."
"From every sentence (of the Upanisads of the Vedanta) deep, original and sublime thoughts arise, and the whole is pervaded by a high and holy and earnest Spirit. In the whole world there is no study so beneficial and as elevating as that of the Upanishads (the Vedanta). (They) are products of the highest wisdom. It is destined sooner or later to become the faith of the people."
