Of everything credited to Akshobhya Tirtha, no single episode is as consistently and independently recorded as his public debate with the Advaita scholar Vidyaranya (1302-1387) on the meaning of the Upanishadic text "tat tvam asi," "that thou art." Advaita Vedanta reads this phrase as proof of the soul's ultimate identity with Brahman. Dvaita Vedanta reads it very differently, as a statement of similarity or relationship, never of literal oneness.

| Location | Mulbagal, near Kolar, Karnataka |
| Verdict | Recorded in favor of Akshobhya Tirtha, in a verse still quoted in traditional circles |
| Physical evidence | A commemorative stone pillar at Mulbagal, badly damaged but still standing |
| Independent textual record | Vyasa Tirtha's Jayatirtha-Vijaya, the Raghavendra-Vijaya, and the Sri Vaishnava work Acharya-Vijaya-Champu |
Two Traditions, One Question #
Vidyaranya was among the most formidable Advaita scholars of his era. History remembers him above all for his role in the founding of the Vijayanagara Empire in 1336. Akshobhya Tirtha, by the account both Uttaradi Math's own tradition and B. N. K. Sharma's academic history preserve, was his acknowledged contemporary and intellectual match. Their disagreement centered on a single Upanishadic phrase, "tat tvam asi," already one of the sharpest points of contention between the whole Advaita and Dvaita schools. Does it declare the individual soul and Brahman to be one and the same, as Shankaracharya's followers held? Or does it point instead to a relationship of dependence and similarity between two things that remain genuinely, eternally different, as Madhvacharya's followers held? Neither side treated this as an abstract technicality. For both schools, the entire architecture of their philosophy stood or fell on how this one phrase was read.
An Arbitrated Verdict #
Rather than leaving the dispute unresolved, both scholars agreed to submit their arguments to Vedanta Desika, the celebrated Sri Vaishnava logician and poet, as arbitrator. That detail alone says something about the intellectual seriousness with which fourteenth-century Indian philosophers treated public disputation. Tradition holds that Vedanta Desika's verdict favored Akshobhya Tirtha, recorded in a Sanskrit verse still quoted by traditional Dvaita scholars today. This tradition is not confined to a single sectarian source. B. N. K. Sharma's academic history notes that it is corroborated by the Vedantadesika-Vaibhavaprakashika of Macharya (sixteenth century) and by an even earlier, fifteenth-century work associated with the Parakala Matha in Mysore, institutions with no particular reason to favor a rival Dvaita pontiff's reputation.
A Pillar, and an Honest Note on Dating #
What sets this episode apart from most of what survives about Akshobhya Tirtha is that it left a physical, epigraphic trace: a stone pillar at Mulbagal, commemorating the victory, that Sharma describes as still discoverable today, though "in a grossly mutilated form." The event is also recorded in Vyasa Tirtha's own Jayatirtha-Vijaya, written about a century later by a celebrated successor in the same Madhva tradition rather than by a direct personal disciple of Jayatirtha, but still an early and respected source close to Akshobhya Tirtha's own lineage, as well as in the later Raghavendra-Vijaya and, notably, in a Sri Vaishnava text, the Acharya-Vijaya-Champu, that had no doctrinal reason to invent a Dvaita victory. Sources genuinely differ on the exact date, and that is worth stating plainly rather than smoothing over. Popular retellings often date the debate to 1336 CE, the same year as Vijayanagara's founding. But Sharma's own careful chronological analysis leaves the exact year open, noting that depending on which dating scheme is used for the pontiffs before Akshobhya Tirtha, the debate could fall anywhere from the 1320s to the 1360s. What is well corroborated, across multiple independent traditions, is the debate's basic shape and its outcome, not its precise calendar date.
