Ordination hall

The ordination hall (Pali: sīmā) is a Buddhist building specifically consecrated and designated for the performance of the Buddhist ordination ritual (upasampadā) and other ritual ceremonies, such as the recitation of the Pāṭimokkha.

[1][2] The ordination hall is located within a boundary (sīmā) that defines "the space within which all members of a single local community have to assemble as a complete Sangha (samagga sangha) at a place appointed for ecclesiastical acts (kamma).

[2] Shan ordination halls, called sim (သိမ်ႇ), are exclusively used for events limited to the monkhood.

[6][7] In Thailand, ordination halls are called ubosot (Thai: อุโบสถ, pronounced [ʔù.boː.sòt]) or bot (โบสถ์, [bòːt]), derived from the Pali term uposathāgāra, meaning a hall used for rituals on uposatha ("Buddhist sabbath") days.

A ninth stone sphere, usually bigger, is buried below the main Buddha image of the ubosot.
