A version of the story found in Daoxuanʼs 道宣 Ji Shenzhou sanbao gantong lu 集神州三寶感通錄(T 2106.52.404b14–405a29), translated in part by Lipiello, 179–181, relates that after his return to life, Liu/Huida was told to search for ancient stūpas and Buddha statues by an Indian monk. He searched, fruitlessly at first, until he heard the miraculous sound of bells. He built a monastery on the spot marked by the sound, and after three days a jeweled stūpa emerged from the earth. Relics were also discovered, which had been brought to China by King Aśoka himself and some holy men with supernatural powers, who had flown over the ocean. Daoxuan goes on to relate that towards the end of the 太元 period (376–396) of the E. Jin 東晉, Huida discovered another set of relics, along with three steles (the central stele containing the reliquary box), hidden under the earth at the site of Changgansi 長干寺, which was the location of an Aśokan stūpa built by Emperor Jianwen 简文帝 (r. 371–372). The chronology of these accounts is confusing. While Liu Sahe is said to have died and returned to life around 281, the monk Huida, with whom he is identified, is supposed to have been active during the Taiyuan 太元 period (376–396) of the Eastern Jin 東晉, including the later part of that period.
