Akshobhya Tirtha's public debate with the Advaita scholar Vidyaranya (1302-1387) is recorded more consistently, and by more independent sources, than any other episode credited to him. The debate was 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.

Two Traditions, One Question #
Vidyaranya was among the strongest Advaita scholars of his time. History remembers him above all for his role in the founding of the Vijayanagara Empire in 1336. Both Uttaradi Math's own tradition and B. N. K. Sharma's academic history describe Akshobhya Tirtha as living in the same period as Vidyaranya, and as his recognized equal in learning. Their disagreement was about a single Upanishadic phrase, "tat tvam asi," which was already one of the sharpest points of dispute between the Advaita and Dvaita schools as a whole. 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 truly and eternally different, as Madhvacharya's followers held? Neither side treated this as a small technical point. For both schools, the whole structure of their philosophy depended on how this one phrase was read.
An Arbitrated Verdict #
The two scholars did not leave the dispute unresolved. Both agreed to present their arguments to Vedanta Desika, the celebrated Sri Vaishnava logician and poet, and to let him judge between them. This detail alone shows how seriously Indian philosophers of the fourteenth century took public debate. 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 found only in the sources of one group. B. N. K. Sharma's academic history notes that it is confirmed by the Vedantadesika-Vaibhavaprakashika of Macharya (sixteenth century). It is also confirmed by an even earlier, fifteenth-century work associated with the Parakala Matha in Mysore. Both works come from institutions that had no particular reason to favor the reputation of a rival Dvaita pontiff.
A Pillar, and an Honest Note on Dating #
Unlike most of what survives about Akshobhya Tirtha, this episode left a physical record in stone. A stone pillar at Mulbagal marks the victory. Sharma describes it as still to be found today, though "in a grossly mutilated form." The event is also recorded in Vyasa Tirtha's own Jayatirtha-Vijaya. Vyasa Tirtha wrote it about a century later. He was not a direct personal disciple of Jayatirtha, but a celebrated later successor in the same Madhva tradition. Even so, his book is an early and respected source, close to Akshobhya Tirtha's own lineage. The event also appears in the later Raghavendra-Vijaya. Notably, it even appears in a Sri Vaishnava text, the Acharya-Vijaya-Champu, whose own teachings gave it no reason to invent a Dvaita victory. The sources really differ on the exact date, and we say so plainly. Popular retellings often date the debate to 1336 CE, the same year as Vijayanagara's founding. But Sharma's own careful study of the dates leaves the exact year open. He notes that the debate could fall anywhere from the 1320s to the 1360s, depending on which dating scheme is used for the pontiffs before Akshobhya Tirtha. The basic shape of the debate and its outcome are well confirmed by several independent traditions. Its exact calendar date is not.
