The word Vedanta literally means the end of the Vedas and originally referred to the Upanishads. Vedanta was concerned with the jñānakāṇḍa or Vedic knowledge part called the Upanishads. The denotation of Vedanta subsequently widened to include the various philosophical traditions based on to the Prasthanatrayi.
The Upanishads may be regarded as the end of Vedas in different senses:
Vedanta is one of the six orthodox (āstika) schools of Indian philosophy. It is also called Uttara Mīmāṃsā, the 'latter enquiry' or 'higher enquiry'; and is often contrasted with Pūrva Mīmāṃsā, the 'former enquiry' or 'primary enquiry'. Pūrva Mīmāṃsā deals with the karmakāṇḍa or rituals part (the Samhita and Brahmanas) in the Vedas.
