The full moon of the month of Vaisakh has a three-fold significance for Buddhists because this was the day when Buddhist God, Buddha was born, attained enlightenment and attained Nirvana.
On the day of Buddha Purnima, Buddhists arrange Panchasheel, Ashtasheel, Sutrapath, Sutrasraban, collective prayers and various other religious ceremonies. Many Buddhists organise three-day festivities. Many social and cultural events are also organised. Fairs for the children are also organised. The Bodhidroom Mela at village Baidyapara in Chittagong is one of the popular fairs. Some people visit the famous ruins of the Mahasthan, Paharpur and Mainamati, which are relics of the finest specimens of Buddhist civilisation and culture.
