經律異相 6.34

6.34

In a past age, there was King Jinmei. After Kāśyapa Tathāgata entered parinirvāṇa, this king built a stūpa of gold and silver, one thousand yojanas in length and breadth and one yojana high. He stacked silver and gold to make a moat, which remains underground to this day. At that time, the Tathāgata brought forth this stūpa and displayed it to the four assemblies; Kāśyapa's whole-body relics were dignified as of old. (Extracted from the Mahīśāsaka Vinaya, fascicle 30)
