From February 4–10, 2026, the sacred Devnimori Relics of Lord Buddha were exhibited at the Gangaramaya Temple, Colombo, Sri Lanka, in a landmark act of India's cultural diplomacy. The relics, normally enshrined at The Maharaja Sayajirao University of Baroda, Vadodara, Gujarat, were transported to Sri Lanka with full state honours. Over one million people participated in the public veneration during the week-long exposition, and the relics returned to India on February 11, 2026.

The Devnimori archaeological site is located near Shamlaji in Aravalli district, Gujarat. First excavated in 1957 by archaeologist Prof. S.N. Chowdhry, the site revealed Buddhist structures and a relic casket of green schist bearing the inscription 'dashabala sharira nilay' (abode of the Buddha's bodily relic), containing a copper box with holy ashes. The relics testify to the flourishing of Buddhism in western India during the early centuries of the Common Era.

The exposition is part of India–Sri Lanka civilisational and diplomatic outreach, deepening people-to-people ties with one of India's key Buddhist-heritage neighbours. It also carries an indirect connection to Rajasthan's own Buddhist heritage at sites like Bairat (Viratnagar), where Ashoka's edicts have been found.
