Upanishads 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. The Upanishads are considered by orthodox Hindus to contain revealed truths (Sruti) concerning the nature of ultimate reality (brahman) and describing the character and form of human salvation (moksha). The Upanishads are found mostly in the concluding part of the Brahmanas and Aranyakas and have been passed down in oral tradition.
