MADHU PURNIMA
In September, another interesting event is commemorated by Madhu Purnima. There were quarrelsome monks who had not attained Arhatship among the blessed ones disciples and to teach them a lesson. He went away alone in to the jungle. There he literally lived with animals. The wild animals of the forest brought him food and he lived in the forest for many weeks. The monks were still quarreling and the laymen, seeing their bad behavior ceased to support them. The monks realized their bad conduct and sent a deputation to the Buddha imploring them to return. When he took leave of his animal friends, some of them died brokenhearted and because of their good Karma they were reborn in the Deva realms. Indian Buddhists specially in Chittagong region, this day offer honey to the Buddhists monks which in memory of this event.
