Internment
After the end of the international tour, the relics were returned to India. However the Burmese government requested a portion of the relics should be given to Burma. The Maha Bodhi Society of India agreed to this, and the then Prime Minister of Burma went in person to Calcutta to receive them. The Burmese portion was ceremonially transferred to him in October 1950, and was later enshrined in the Kaba Aye Zedi (World Peace Pagoda), built on the site of the Sixth Buddhist Council, close to Rangoon. Extensive ceremonies connected with the crowning of the pagoda and the installation of the relics lasted from the 5th to 11th of March 1952.
Another portion was given to Sri Lanka to be enshrined in a new stupa built by the Maha Bodhi Society of Sri Lanka to receive them. They are currently housed in the temple of the Maha Bodhi Society, Colombo, awaiting the completion of the building.
On 30 November 1952, the remaining relics were enshrined at Sanchi on completion of the new Chetiyagiri Vihara built to store them.
