Vedanta or Uttara Mīmāṃsā is one of the six orthodox schools of Indian philosophy. It represents the divergent philosophical views of more than 10 schools—all developed on the basis of a textual connection called the Prasthanatrayi. The Prasthanatrayi is a term for the Principal Upanishads, the Brahma Sutras. Vedanta does not stand for one comprehensive or unifying doctrine, over time, Vedanta adopted ideas from other orthodox schools like Yoga and Nyaya, and, through this syncretism, became the most prominent school of Hinduism. Many extant forms of Vaishnavism, Shaivism and Shaktism have been shaped and influenced by the doctrines of different schools of Vedanta. 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 philosophical traditions based on to the Prasthanatrayi. The Upanishads may be regarded as the end of Vedas in different senses and these mark the culmination of Vedic thought. These were taught and debated last, in the Brahmacharya stage, Vedanta is one of the six orthodox schools of Indian philosophy. It is also called Uttara Mīmāṃsā, the latter enquiry or higher enquiry, and is contrasted with Pūrva Mīmāṃsā. Pūrva Mīmāṃsā deals with the karmakāṇḍa or rituals part in the Vedas, the Upanishads, the Bhagavadgita and the Brahma Sutras constitute the basis of Vedanta. All schools of Vedanta propound their philosophy by interpreting these texts, collectively called the Prasthanatrayi, literally, the Upanishads, or Śruti prasthāna, considered the Sruti foundation of Vedanta. The Brahma Sutras, or Nyaya prasthana / Yukti prasthana, considered the foundation of Vedanta. The Bhagavad Gita, or Smriti prasthāna, considered the Smriti foundation of Vedanta, the Brahma Sutras attempted to synthesize the teachings of the Upanishads. The diversity in the teaching of the Upanishads necessitated the systematization of these teachings and this was likely done in many ways in ancient India, but the only surviving version of this synthesis is the Brahma Sutras of Badarayana. The Bhagavad Gita, due to its syncretism of Samkhya, Yoga, the Upanishads do not present a rigorous philosophical inquiry in the form of identifying various doctrines and then presenting arguments for or against them. They form the basic texts and Vedanta interprets them through rigorous philosophical exegesis, varying interpretations of the Upanishads and their synthesis, the Brahma Sutras, led to the development of different schools of Vedanta over time of which three, four, five or six are prominent. Some scholars are inclined to consider it as a rather than a school of Vedanta
