This is a short illustrated talk on the significance of the Full Moon Day in December (Uduvap), which is the first part in a planned series of talks explaining what the various Full Moon days commemorate.
In Sri Lanka this is one of the most important Full Moon Days of the year as it marks the arrival of the Arahat nun Sanghamittā along with a sapling from the Bodhi tree from Bodhgaya.
The nuns order was very successful and a mainstay of the Sāsana in Lanka for over 1,000 years; and the Bodhi Tree itself became the Palladium of the nation, and is still there 2,200 years later.
