A considerable portion of the major Upanishads is devoted to the Upasanas or meditative exercises which are called Vidyas. A good number of these Vidyas in the sense of in-depth higher level of learning are discussed in three important Upanishads namely, Chandogya, Brhdaranyaka and Taittriya Upanishads and in the Vedanta Sutras or Brahmasutras. Practice of these Vidyas have been seen in relation to yajnas and some of them yield Kamyaphala (fruits of yajna) as have been given in Sutra 3.3.60. Hence some of these Vidyas are also called Kamya Vidyas. Shri Adi Shankaracharya in his bhasyas interprets these Vidyas as practical exercises of meditation. Also called as Brahmavidya, 32 such Vidyas have been given.<ref>Aiyar, Narayanaswami K., (1919 First Edition) ''The Thirty-two Vidyas.
