It is dedicated to the preaching of the sacred teaching of Kalachakra. The third major holiday is Gandun-Shunserme, devoted to the birth and enlightenment of Buddha and his attainment of nirvana. It is celebrated in early summer. The fourth holiday Maidari is dedicated to Maidari, the Buddha of the future. It is always celebrated for two days in midsummer.
People spend the first day in many hours of devout prayer.
On the second day the gilded statue of Maidari is solemnly carried out of the temple and placed on a chariot twined with silk ribbons. It is surrounded by lamas in ceremonial dress. A green horse of plaster is harnessed to the chariot, and the procession sets off around the datsan. This ceremony symbolizes Maidari's tour of the universe and the spread of his grace throughout it. Several thousand people gather in the datsan for the procession.
