Why was stupas also called tope?

Stupas are also called "topes" due to the influence of the ancient Indian term "stūpa," which refers to a mound or heap. The term "tope" is derived from this Sanskrit Word and is commonly used in regions like India and Nepal to describe these hemispherical structures that serve as reliquaries, housing sacred relics. Both terms emphasize the stupa's significance as a monument in Buddhist architecture, symbolizing the enlightened mind of the Buddha.
