Mani Rimdu is the biggest festival of the year for the Sherpas of the Khumbu region. Sherpas from the Khumbu region congregate at Thyangboche Monastery, the picturesque monastery situated on a spur at 3,870 meters. The three-day celebrations of Mani Rimdu follow the ten days of non-stop prayer sessions addressed to the patron deities seeking blessing from the god of all mankind. The deity propitiated is Guru Rinpoche, the founder of Tibetan Buddhism. The ceremony begins with the blowing of horns in the afternoon after which the abbot of the monastery accompanied by other monks chant prayers. The congregation is blessed and given holy water and auspicious pellets for good luck and longevity. An orchestra of cymbals, horns, flutes, and conch shells announces the start of the second day's celebrations. Monks in colorful robes and huge glowering masks perform dances symbolizing the destruction of evil. On the last day, tormas (figures made of dough) are consigned to a sacred fire. This implies the end of negative forces and the advent of a blessed new year. The festival falls in October and November.
