Stupa
At its simplest, a stupa is a dirt burial mound faced with stone. In Buddhism, the earliest stupas contained portions of the Buddha's ashes, and as a result, the stupa began to be associated with the body of the Buddha. Adding the Buddha's ashes to the mound of dirt activated it with the energy of the Buddha himself.
