Bhāṣyakārar — The Author of the Śrī Bhāṣya
Bhāṣyakārar (Sanskrit: bhāṣya = authoritative commentary + kāra = maker; 'the one who composed the bhāṣya') is the most widely used reverential title for Śrī Rāmānujāchārya (1017–1137 CE) within the Śrī Vaiṣṇava tradition. The title is specific: it identifies Rāmānuja first and foremost as the author of the Śrī Bhāṣya, his Viśiṣṭādvaita commentary on the Brahmasūtras of Bādarāyaṇa (Veda Vyāsa).
The Śrī Bhāṣya: The Śrī Bhāṣya is Rāmānuja's magnum opus — a systematic, exhaustive commentary on all 545 Brahmasūtras that establishes Viśiṣṭādvaita Vedānta as the correct interpretation of the Upaniṣads, the Bhagavad Gītā, and the Brahmasūtras together (the prasthāna-traya). Rāmānuja proceeds to refute Advaita (Śaṃkarāchārya), Bhedābheda, and other schools while establishing that Brahman is Saguṇa (endowed with infinite auspicious qualities), that jīvas and jagat are real, and that they exist as the body and modes of Brahman — the Viśiṣṭādvaita position.
The Title as Honor: In Śrī Vaiṣṇava parlance, to say simply 'Bhāṣyakārar said...' (Bhāṣyakārar aruḷicceytadu) immediately invokes Rāmānuja's authority. This is a mark of the absolute centrality of the Śrī Bhāṣya to the tradition — it is the philosophical anchor, the text that gave the sampradāya its rigorous Vedāntic foundation. Rāmānuja is also called Udaiyavar, Emperumānār, and Tiruvaraṅgattu Amudanār, but Bhāṣyakārar is the title used specifically in scholarly and philosophical contexts.
Drawing on the Bōdhāyana Tradition: Rāmānuja in the Śrī Bhāṣya's introduction famously states that he is following and drawing upon the ancient Vṛtti of Bōdhāyana — an earlier sage who had written an explanation of the Brahmasūtras in the same Viśiṣṭādvaita spirit. This grounds the Śrī Bhāṣya not as a new invention but as the recovery and continuation of an ancient authoritative tradition.
