In Sri Lanka, every full moon day is a Poya day — a public holiday when shops close, temples fill with people dressed in white, and the whole country slows down a little. The word comes from the Pali uposatha, the observance day that the Buddha encouraged lay followers to keep. Traditionally the new moon and the two half-moon days are also Uposatha days, but the full moon is the one most widely observed. Wherever you live, a Poya day is an invitation to set aside ordinary busyness and give one day fully to the Dhamma.
What the Uposatha is for
The Buddha described the Uposatha as a day for purifying the mind. For one day and night, a lay person lives a little more like a monk or nun: simpler, quieter and more restrained. In the discourses he compares this to washing: just as a dirty cloth is cleaned with soap and water, the mind is cleansed by recollecting the qualities of the Buddha, the Dhamma and the Sangha, and by keeping good conduct. The point is not hardship for its own sake, but creating space in which calm and wisdom can grow.
You can check the dates for the coming year on our Poya calendar, and plan ahead so that work and family duties do not crowd the day out.
The eight precepts
On ordinary days lay Buddhists aim to keep the five precepts. On Poya days many take the eight precepts (in Sinhala, ata sil). Each one begins with the same words of commitment: “I undertake the training rule to abstain from…”. The eight are:
- Abstaining from killing or harming living beings.
- Abstaining from taking what is not given.
- Abstaining from all sexual activity (not only misconduct, as in the five precepts).
- Abstaining from false speech.
- Abstaining from alcohol and intoxicating drugs that cloud the mind.
- Abstaining from eating at the wrong time — that is, taking no solid food from midday until dawn the next day.
- Abstaining from dancing, singing, music and entertainments, and from wearing garlands, perfumes, cosmetics and ornaments.
- Abstaining from high and luxurious seats and beds.

I undertake the training rule to abstain from taking life. — the first precept
The extra precepts are gentle forms of renunciation. Not eating in the afternoon lightens the body for meditation. Setting aside music, entertainment and adornment turns attention inward. Sleeping on a simple mat rather than a soft, high bed reduces indulgence. Together they show us, in a very practical way, how much of our restlessness is driven by small cravings.
A day at the temple
In Sri Lanka, people who are “observing sil” usually arrive at the temple early in the morning, wearing simple white clothes as a sign of purity and equality. A typical day may include:
- Taking the Three Refuges and the eight precepts from a monk, by repeating the Pali after him.
- Offering flowers, lamps and incense at the shrine, and paying respect at the bodhi tree and stupa.
- Offering a midday meal to the monks, followed by a simple meal for the observers before noon.
- Listening to a Dhamma talk (bana) and reading or discussing the teachings.
- Periods of sitting and walking meditation, often mindfulness of breathing and loving-kindness.
- Evening chanting, after which the precepts are kept until dawn the next morning.
If it is your first time, simply sit near the back and follow what others do. Temple communities are usually delighted to help a newcomer, and nobody expects you to know every chant.
Keeping Poya at home
Not everyone lives near a temple, and many people cannot take a whole day off work. The Uposatha can still be kept meaningfully at home. You might take the eight precepts in the morning in front of your home shrine, or keep the five precepts with extra care if eight are not possible for you. Some people keep the precepts only from the evening before until the evening of the Poya day. What matters most is sincere intention.
- Wake a little earlier than usual, wash, and dress simply — white if you have it.
- Light a lamp, recite the homage to the Buddha and the Three Refuges, and undertake the precepts.
- Plan a light, early main meal and finish eating before noon.
- Turn off the television, music and social media for the day.
- Set aside time for meditation, Dhamma reading or an online talk.
- End the day by reflecting on your conduct and sharing the merit with all beings.
If you break a precept
Precepts are training rules, not vows that bring punishment. If you forget and eat in the afternoon, or say something careless, simply notice it, recommit, and carry on. Over time, regular Poya observance becomes a quiet monthly rhythm that steadies the whole of life.
Practical takeaway: look at the next full moon on the calendar today, and decide one concrete way you will mark it — even if it is only a morning of precepts and an hour of silence.
