Chapter I
What it celebrates
According to the Theravada tradition, nine months after his awakening the Buddha was staying at the Bamboo Grove, Veluvana, near Rajagaha. On the full moon of the month of Magha, 1,250 monks, all of them arahants, came to him on their own. To this assembly the Buddha recited the Ovada Patimokkha, a summary of the teaching that includes the verse also found in the Dhammapada (183): “Not to do any evil, to cultivate good, to purify one’s mind: this is the teaching of the Buddhas.”
The day is therefore also a celebration of the Sangha, the community of monks and nuns, which is why some Western Buddhist communities call it Sangha Day.
Chapter II
How it is kept
Lay Buddhists go to the temple in the morning to offer food to the monks, give alms and take the precepts; some keep eight precepts for the day and night. Monks give sermons on the Ovada Patimokkha.
At dusk comes the wian tian, “circling with candles”: holding a lit candle, three sticks of incense and a flower, worshippers walk three times clockwise round the ordination hall or a stupa, once for each of the Three Jewels, the Buddha, the Dhamma and the Sangha, reciting their qualities. The temple grounds glow with hundreds of small flames.
Chapter III
Around the world
In Thailand the day is a public holiday, and the sale of alcohol is banned. Cambodia keeps it as Meak Bochea and Laos as Boun Makha Bousa. In Sri Lanka the February full moon, Navam Poya, also recalls the first assembly of the Buddha’s disciples, and Colombo’s Gangaramaya temple holds the Navam Perahera, a procession of drummers, dancers and elephants.
