The full moon day known as Poya/Pohoya in Buddhism are days for reflection and meditation and renewed dedication to the practice. It is observed in the Theravada form of Buddhism, and hails from the time of the Buddha’s life. In Sri Lanka these Poya days also coincide with historical milestone of Buddhism in relation to the country and is therefore observed with great significance as a national holiday every month.
IN BUDDHISM: This day commemorates the Buddha’s visit to Uruwela Danawwa (place of habitation). During his visit the Buddha directs the Kassapa brothers on the correct path. The Kassapa brothers; Uruwela Kassapa, Gaya Kassapa and Nadi Kassapa were arrogant Jatila ascetics with one thousand followers.
IN SRI LANKA: This day observes the Buddha’s first visit to Sri Lanka to the Mahiyanganya region. At the time the prehistoric inhabitants in Lanka were the Yakkha (devil) and the Nagha (serpent) tribes. These tribes were in constant confrontation and this visit was on the invitation of the God Sumana Saman to put an end to this hostility. The Buddha was able to create peace among them. The legend says the Yakkhas unable to understand his words dispersed to the Giri Divayina (island) whilst the Devas (gods) and Naghas accepted Buddhism. God Saman requested for a relic to worship and the Buddha gave him a lock of his hair which he in return enshrined in the Mahiyangana Dagaba (shrine).
IN BUDDHISM: The two very significant incidents that took place on the Navam Poya were the first ever Buddhist congregation where a code of ethics for Buddhist monks was proclaimed and the appointment of two chief disciples (aggasavakes) of the Buddha as namely Sariputta and Moggallana.

First comes the birth of Siddhartha Gautama. The second event was Siddharta Gautama’s supreme attainment of nirvana to become the Buddha. The third event was Lord Buddha’s Parinibbana (death) over 2,500 years ago.

This request had been refused by the Buddha many times earlier on the grounds that he did not wish for women to enter homeless life in this doctrine and discipline that has been taught.
