Stupa at Dusk
A stūpa is a mound-like or hemispherical structure containing relics (such as śarīra – typically the remains of Buddhist monks or nuns) that is used as a place of meditation. A related architectural term is a chaitya, which is a prayer hall or temple containing a stupa.
In Buddhism, circumambulation or pradakshina has been an important ritual and devotional practice since the earliest times, and stupas always have a pradakshina path around them.
Religious buildings in the form of the Buddhist stupa, a dome shaped monument, started to be used in India as commemorative monuments associated with storing sacred relics of the Buddha. After the parinirvana of the Buddha, his remains were cremated and the ashes divided and buried under eight mounds with two further mounds encasing the urn and the embers. The relics of the Buddha were spread between eight stupas, in Rajagriha, Vaishali, Kapilavastu, Allakappa, Ramagrama, Pava, Kushinagar, and Vethapida.
