This study aims to examine the early use of Da-bo tap and their transformation by analyzing the various meanings of the term pagoda in Chinese translations, the Sanskrit version of the Lotus Sutra, as well as Dabotap in the Mogao Caves of Dunhuang. In addition, we aim to highlight changes in Dabotap usage, which started out as residential spaces, but transformed into burial spaces over time. The details can be summarized as follows. First, early Buddhist monuments were usually either pagodas serving as burial places for the dead or shrines that were not. A Dabotap is a type of pagoda enshrining the body of Prabhutaratna, and was initially used as a residential space, rather than a burial place for the dead. Second, the terms stupa and caitya are clearly distinguished from each other in the Sanskrit scriptures, and stupa is also further classified into dhatu, sarisa, and atmabhava based on the object being enshrined. In Gyeon-bo-tab-pum, the preconditions for caitya to transform into stupa is presented by explaining that worshipping the space enshrining the body of Prabhutaratna is worthy of the same status as the space enshrining sarira. Third, the Mogao Caves of Dunhuang had been depicted from the Western Wei of the Northern Dynasties until the time of the Yuan Dynasty. It was used as a residential space until the early Sui Dynasty, but was used as both residence and burial places until the Tang Dynasty when pagodas were first being constructed with wheel or circles forms on top, which then gradually changed into stupa (grave towers).
