Losar is a major festival in Arunachal Pradesh as it marks the Tibetan New Year. Tribes like Monpa, Sherdukpens, Memba, Khamba and Nah following the Mahayana sect of Buddhism celebrate this festival with all pomp. This three-day festival begins on February 11 each year. On the first day of the festival, the priests make offering to the highest priest called the Dharmapala or Palden Lhamo, whereas the masses visit friends and family and wish them Tashi Delek (best wishes). Also according to the local tradition, sprouted barley seeds and buckets of tsampa (roasted barley flour with butter) and other grains are offered on home altars to ensure a good harvest.
On the second day of the festival, which is also called Gyalpo Losar, national leaders and kings are honored. On the third and final day of the festival known as Choe-Kyong Losar, people make offerings to Dharmapala and tie prayer flags on rooftops and across the locality. Although the spiritual observance ends on the third day, the celebration can extend for 10 to 15 days.
