Dhamma study and meditation. Sometimes the abbot or a senior monk will give a Dhamma talk to the visitors. Laity who stay at the monastery will have to abide by the traditional eight Buddhist precepts. The life of the monk or nun in a community is much more complex than the life of the forest monk. In the Buddhist society of Sri Lanka, most monks spend hours every day in taking care of the needs of lay people such as preaching bana, accepting alms, officiating funerals, teaching dhamma to adults and children in addition to providing social services to the community.
