Buddha Unfolding Festival is celebrated in Tashilhunpo Monastery from the fourteenth to the sixteenth day of the fifth Tibetan month. Unbelievable giant Thangkas of Amitayus, Sakyamuni and Maitreya are displayed on the monastery's Thangka Walls. Thousands of pilgrims rush to the monastery to give their offerings to the Buddhas for the accumulation of their merits. The tradition has lasted for 500 years.
