Upanishads

The Upanishads (Sanskrit: उपनिषद्, IAST: Upaniṣad, ) are a collection of philosophical texts which form the theoretical basis for the Hindu religion. They are also known as Vedanta, the end of the Veda. In the purest sense, they are not Sruti (revealed truths) but rather commentaries which explain the essence of the veda (revealed knowledge). The Upanishads are found mostly in the concluding part of the Brahmanas and in the Aranyakas. All Upanishads have been passed down in oral tradition.
