The envoys from the Great Han, including Cai Yin, arrived at Jingshui Country and were led by the City Lord to the Pure Water Temple, where they met Shemoteng and Zhufalan, disciples of Bodhidharma. These two were chosen by Tathagata to spread Buddhist Law in the Eastern Land. After their mission was complete, they were to ascend to Mount Meru in the Western Heaven and receive the incense power and wishes from all below, achieving Buddhahood and becoming Ancestors.
