As well as that, the Sherpas are associated with Losar and enjoy Losar in the high altitudes of the Nepal Himalayan Range. Prior to the Chinese invasion of Tibet in 1950, Losar began with a morning ritual ceremony at Namgyal Monastery, led by the Dalai Lama and other high-ranking lamas, with government officials participating, to honor the Dharmapala (dharma-protector) Palden Lhamo. After the Dalai Lama was exiled, many monasteries were destroyed and monks imprisoned. Since that time, Tibetan Buddhist practice in Tibet has been difficult to observe publicly.
