What is "cetiya"

Cetiya, "reminders" or "memorials" ( Sanskrit caitya), are objects and places used by Theravada Buddhists to remember Gautama Buddha. According to Prince Damrongrāchānuphāp, four kinds are distinguished in the Pāli Canon: "Relic [Dhatu], Memorial [Paribhoga], Teaching [Dhamma], and Votive [Udesaka]." Griswold, in contrast, states that three are traditional and the fourth, the dhamma, was added later to remind monks that the true memory of Gautama Buddha can be found in his teachings. While these can be broadly called Buddhist symbolism, the emphasis tends to be on a historical connection to the Buddha and not a metaphysical one.
