大慧普覺禪師宗門武庫 1.16

1.16

When venerable masters in various regions display extinction and their whole bodies are bathed in fire, they obtain extremely numerous relics (śarīra). Only Chan Master Zhenjing's relics were as large as beans, five-colored, crystal clear, and also hard and solid. Chan Master Zu of Gushan was an eminent disciple of Zhenjing; he gathered many of them, stored them in a lapis lazuli bottle, and carried them with him to make offerings. When Miaoxi visited Gushan, he once tested them: placing them on an iron anvil, he raised a hammer and struck them. The anvil and hammer were both dented, yet the relics were unharmed. How could this not be brought about by his clear and lucid daily practice and his transcendent realization of the Way?
