Upanishads

Sri Rajaji presents, in the Upanishads, the grandeur of the ancient wisdom of the great Seers of Bharatvarsha.
In the Upanishads, we have a scripture which, among all the holy scriptures of the world, displays the most scientific spirit in connection with spiritual enquiry. The sages, whose thoughts and teachings we read in the Upanishads, seem to be as much inspired by constructive doubt as the most modern men of science. Their questions and answers indicate that they lived in an age when, alongside of conformism and the rigid maintenance of old practices, men thirsted for truth.
