There are mainly six branches of Hindu Philosophy. These six schools of philosophy have been the result of ancient Indian thought and usually termed as "Sad Darsana". These are:
- Samkhya
- Yoga
- Vaiseshika
- Nyaya
- Purva Mimamsa
- Vedanta
Among the above six schools of Hindu Philosophy, Vedanta is by far very popular. The Vedanta accepts the authority of the knowledge portions of the Vedas, called Upanishads.
