Vedānta (Sanskrit: veda + anta, “end of the Vedas“) designates the prasthāna-trayam — the triple canonical foundation of Indian philosophy comprising the Upaniṣads (śruti), the Brahmasūtras (nyāya-prasthāna), and the Bhagavad Gītā (smṛti-prasthāna). As uttara-mīmāṃsā, Vedānta is distinguished from the ritual-focused pūrva-mīmāṃsā of Jaimini by its central concern with Brahman-knowledge and liberation.
Viśiṣṭādvaita is one of the three major Vedāntic traditions alongside Advaita (Śaṅkara) and Dvaita (Madhva). Rāmānuja's Śrī Bhāṣyam — a monumental commentary on the Brahmasūtras — established the Viśiṣṭādvaita reading systematically: Brahman is the qualified, all-inclusive absolute whose body comprises all conscious (cit) and inert (acit) realities; individual selves are real, distinct, and eternally related to Brahman as body to soul; liberation (mokṣa) is a fully conscious state of loving service to Bhagavān in Śrī Vaikuṇṭham.
Rāmānuja's Vedāntic synthesis was prepared by Yāmunāchārya's Ātmasiddhi, Saṃvit Siddhi, and Āgama Prāmāṇyam, and is further expounded in Rāmānuja's own Vedārthasaṃgraha, Gītābhāṣyam, and Vedāntadīpa. The Vedāntic tradition thus flowing through the Sri Vaishnava sampradāya represents the most comprehensive integration of Vedic theology, Āzhvār devotion, and Pañcarātra practice.
