The sacred relics of Arahant Sariputta and Arahant Mahamoggallana — the two chief disciples of the Buddha — will be displayed at the Ganden Monastery in Ulaanbaatar, Mongolia, from 1 to 10 June 2026, in an exposition jointly organised by India's Ministry of Culture, the International Buddhist Confederation (IBC), and the National Museum, New Delhi. The event marks a significant milestone in India-Mongolia spiritual diplomacy, fulfilling a commitment made by Prime Minister Narendra Modi in October 2025.

A Promise Kept: Modi's October 2025 Announcement

During the four-day State Visit of Mongolian President Khurelsukh Ukhnaa to India in October 2025, Prime Minister Modi announced the relics exposition at a joint press conference following bilateral talks at Hyderabad House, New Delhi on 14 October 2025. Modi said: 'The relationship between India and Mongolia is not merely diplomatic — it is a bond of warmth and spirituality. The true depth and breadth of our relationship is reflected in our people-to-people ties.'

He further stated: 'I am pleased to announce that next year, the holy relics of two great disciples of Lord Buddha — Sariputra and Maudgalyayana — will be sent from India to Mongolia. We will also send a Sanskrit teacher to Gandan Monastery to study the Buddhist texts there in depth and carry forward the ancient tradition of knowledge.'

Who Were Arahant Sariputta and Arahant Mahamoggallana

Arahant Sariputta and Arahant Mahamoggallana were born on the same day in adjacent villages in the Magadha region, near present-day Nalanda — Sariputta in Upatissa village and Mahamoggallana in Kolita village. Arahant Sariputta is revered across the Buddhist world as the supreme exemplar of wisdom, analytical insight, and doctrinal mastery. Together, they are regarded as pillars of the early Sangha and the primary carriers of the Buddha's Dhamma.

According to the IBC, 'The Relics of these two chief disciples symbolise the preservation, interpretation and transmission of that Enlightenment into the world. Together, they personify the two inseparable dimensions of Buddha Dhamma: wisdom and realisation; doctrine and direct experience.' The IBC further noted that the relics 'represent the realised Sangha in its purest form' — one of Buddhism's Three Jewels alongside the Buddha and the Dhamma.

Significance for Mongolia

Mongolia's Buddhist identity is historically rooted in devotion, scholarship, monastic discipline, and meditative tradition. The IBC stated that the exposition 'will establish a sacred and tangible connection because they complete the living picture of the Buddha Dhamma' for Mongolian devotees.

This is not the first time India has sent sacred relics to Mongolia. In June 2022, four Kapilavastu Relics of the Buddha were flown to Mongolia on board a C-17 transport aircraft of the Indian Air Force (IAF) for an 11-day exposition — their first visit to the country in 29 years. The relics were displayed alongside Mongolia's revered Buddha Tooth Relic at the Gandantegchinlen Monastery on the occasion of Mongolian Buddha Purnima on 14 June 2022, accompanied by the then Minister of Law and Justice Kiren Rijiju and the 20th Kushok Bakula Rinpoche.

A Broader Buddhist Diplomacy

The relics exposition fits into a wider pattern of India deploying Buddhist heritage as a tool of cultural diplomacy across Asia. In February 2024, a grand state ceremony was held at Sanam Luang, Bangkok, where Somdet Phra Sangharaja Sakon Maha Sanghaparinayok and then-Thai Prime Minister Srettha Thavisin jointly presided over the enshrinement of the relics of the Buddha alongside those of Arahant Sariputta and Arahant Mahamoggallana. The ceremony was organised by the Royal Thai Government in cooperation with the Government of India under the 'Ganga–Mekong Holy Buddha Relics' initiative, as part of celebrations marking the 72nd birthday of Thailand's King.

The historical depth of India-Mongolia ties was captured by the late Atal Bihari Vajpayee — then External Affairs Minister — in 1978, when he said: 'India and Mongolia are ancient lands of the ancient people of Asia... We hold the people of Mongolia in high esteem for preserving in translation as well as in manuscripts, the vast collection of our precious Sanskrit text on our philosophy, poetry, logic and astronomy lost by us over centuries.'

What Comes Next

The June 1–10 exposition at Ganden Monastery will be accompanied by the deployment of a Sanskrit teacher to the monastery — a commitment Modi made alongside the relics announcement. The event is expected to draw thousands of Mongolian Buddhist devotees and further cement the 'spiritual siblings' framing that both governments have embraced as the cornerstone of bilateral ties.
