Brahma Sutras in the context of "Vedanta"

Vyasa (/ˈvjɑːsə/; Sanskrit: व्यास, lit. 'compiler, arranger', IAST: Vyāsa) is a rishi (sage) with a prominent role in most Hindu traditions. He is also known as Veda Vyasa (Sanskrit: वेदव्यास, lit. 'the one who classified the Vedas', IAST: Vedavyāsa) or Krishna Dvaipayana (Sanskrit: कृष्णद्वैपायन, IAST: Kṛṣṇadvaipāyana). Traditionally regarded as the author of the epic Mahābhārata, Vyasa also plays a prominent role as a character. He is also regarded by the Hindu traditions to be the compiler of the mantras of the Vedas into four texts, as well as the author of the eighteen Purāṇas and the Brahma Sutras.

Vyasa is regarded by many Hindus as a partial incarnation (Sanskrit: अंशावतार, IAST: Aṃśāvatāra) of Vishnu. He is one of the immortals called the Chiranjivis, held by adherents to still be alive in the current age known as the Kali Yuga.

Prasthanatrayi (Sanskrit: प्रस्थानत्रयी, IAST: Prasthānatrayī), literally, three sources (or axioms), refers to the three canonical texts of theology having epistemic authority, especially of the Vedanta schools. It consists of:

1. The Upanishads, known as Upadeśa Prasthāna (injunctive texts), and the Śruti Prasthāna (the starting point or axiom of revelation), especially the Principal Upanishads.
2. The Bhagavad Gita, known as Sādhana Prasthāna (practical text), and the Smṛti Prasthāna (the starting point or axiom of remembered tradition)
3. The Brahma Sutras, known as Sūtra Prasthāna (formulative texts) or Nyāya Prasthāna or Yukti Prasthāna (logical text or axiom of logic)

The Upanishads consist of ten, twelve or thirteen major texts, with a total of 108 texts (some scholars list ten as principal – the Mukhya Upanishads, while most consider twelve or thirteen as principal, most important Upanishads). The ten Upanishads are Īśā, Kena, Kaṭha, Praṣna, Muṇḍaka, Māṇḍūkya, Taittirīya, Aitareya, Chāndogya and Bṛhadāraṇyaka.

Brahmavidya (Sanskrit: ब्रह्मविद्या, romanized: Brahmavidyā, lit. 'knowledge of the Ultimate Reality') is a branch of Hindu scriptural knowledge derived primarily through a study of the Upanishads, the Brahma Sūtras, and the Bhagavad Gita.

In the Puranas, this is divided into two branches, the first one dealing with the Vedic mantras and is called para-vidya or 'former knowledge', and the latter dealing with the study of the Upanishads and is called the apara-vidya or 'latter knowledge'. Both para- and apara-vidya constitute brahma-vidya. The Mundaka Upanishad says that "Brahma-vidya sarva-vidya pratistha", which means "The Knowledge of Brahman is the foundation of all knowledge."

Madhvacharya (IAST: Madhvācārya; pronounced [mɐdʱʋaːˈtɕaːrjɐ]; 1199–1278 CE or 1238–1317 CE), also known as Purna Prajna (IAST: Pūrṇa-Prajña) and Ānanda Tīrtha, was an Indian philosopher, theologian and the chief proponent of the Dvaita (dualism) school of Vedanta. Madhva called his philosophy Tattvavāda meaning "arguments from a realist viewpoint".

Madhvacharya was born at Pajaka near Udupi on the west coast of Karnataka state in 13th-century India. As a teenager, he became a Sanyasi (monk) joining Brahma-sampradaya guru Achyutapreksha, of the Ekadandi order. Madhva studied the classics of Hindu philosophy, and wrote commentaries on the Principal Upanishads, the Bhagavad Gita and the Brahma Sutras (Prasthanatrayi), and is credited with thirty seven works in Sanskrit. His writing style was of extreme brevity and condensed expression. His greatest work is considered to be the Anuvyakhyana, a philosophical supplement to his bhasya on the Brahma Sutras composed with a poetic structure. In some of his works, he proclaimed himself to be an avatar of Vayu, the son of god Vishnu.

Ramanuja ([ɾaːmaːnudʑɐ]; Middle Tamil: Rāmāṉujam; Classical Sanskrit: Rāmānuja; c. 1077 – 1157, trad. date 1017-1137), also known as Ramanujacharya, was an Indian Hindu philosopher, guru and social reformer. He is one of the most important exponents of the Sri Vaishnavism tradition in Hinduism. His philosophical foundations for devotional practice were influential in the Bhakti movement.

Ramanuja's guru was Yādava Prakāśa, a scholar who, traditionally, is said to have belonged to the Advaita Vedānta tradition, but probably was a Bhedabheda scholar. Sri Vaishnava tradition holds that Ramanuja disagreed with his guru and the non-dualistic Advaita Vedānta, and instead followed in the footsteps of Tamil Alvārs tradition, the scholars Nāthamuni and Yamunāchārya. Ramanuja is famous as the chief proponent of Vishishtadvaita school of Vedānta, and his disciples were likely authors of texts such as the Shatyayaniya Upanishad. Ramanuja himself wrote influential texts, such as Sanskrit bhāsyas on the Brahma Sutras and the Bhagavad Gita.
