This study focuses on various Sanskrit scripts and mantras contained in various Buddhist paintings, including hanging scrolls and, in particular, the new forms and meanings of the religious paintings stored within the body of Buddha's statue by comparing the scripts and mantras with Josanggyeong (造像經, The Buddhist Canon of Iconography). Buddhas and bodhisattvas depicted on the hanging scrolls made by Uigyeom(義謙) contain Sanskrit scripts in many parts of their images, the head, eyes, and breast in particular. The scripts are connected with the ceremony of opening the eyes of a Buddha or bodhisattva as provided by the records on the eight eyes of Bulbosal-Jeompilbang(佛菩薩點筆方 八眼) and Junjeguseong-Beomja(准提九聖梵字) in Josanggyeong. The painting also reveals along its edges the mantras which are the same as those contained in the canon's three chapters, “Jebulbosal-Bokjangdan-Uisi (諸佛菩薩腹藏壇儀式),” “Myogilsang-Daegyowanggyeon (妙吉祥大敎王經)” and “Samsiljidanseok (三悉地檀釋)” focused on the ceremony of storing offerings in the body of a Buddhist statue. The inscription of Sanskrit scripts and mantras on Buddhist paintings was conducted widely in the 17th and 18th centuries during which the publication of mantra anthologies and manuals of Buddhist rites and ceremonies was also widespread. The tradition of inscribing Sanskrit scripts and mantras on the Buddhist hanging scrolls seems to have been closely related with the ritual dances performed before the scroll as part of a Buddhist prayer service.
