“King Dṛdhasamādāna replied to his son, ‘Don’t feel sad or displeased by it. The golden wheel treasure wasn’t your father’s property. Simply endeavor to enact the correct teaching of a noble king. After practicing that correct teaching, then bathe yourself in fragrant water surrounded by your concubines on the fifteenth-day full moon and ascend the Hall of the Correct Teaching. The miraculous treasure of the golden wheel will spontaneously appear. The wheel will have a thousand spokes and possess a radiant color. It’s made by a heavenly craftsman. It isn’t something that belongs to this world.’
