It is held in Matho Monastery and it is a very colorful festival. The first two days mask dances are held. The masks that the priests wear reflect the faces of Gods and Goddesses. The festival is popular as after two months of isolated meditation, two oracles appear which come to the courtyard where the masked priests dance. It is celebrated on the 15th of the first month of the Tibetan calendar.
