An Ārāma of the Buddhist Order was a monk residence donated by kings and lords, etc. In general, an ārāma was a villa used for vacations and holidays, which bhikkhunis were not allowed to visit for any reason (an offense of pacittiya). Once they were donated, however, monks would live under the trees there and hold their religious meetings and informal discussions there. Sometimes the buildings at the ārāma would be converted into Vihara, Parivena, and so forth. A Buddhist ārāma may have a fence of bamboo or thorns, and a ditch around it. A gateway or intermediate passage may be constructed.
Unlike most sangha property, "sangharama" cannot be divided up into private property nor donated. This is an offense of thullaccaya.
A bhikkuni cannot enter an ārāma of bhikkhus without permission; this is an offense of pacittiya.
