"Question: How can you be certain that the exiles and sentences of death imposed on you are the result of karma created in the past?
Answer: A bronze mirror will reflect color and form. The First Emperor of the Ch'in dynasty had a lie-detecting mirror that would reveal offenses committed in this present life. The mirror of the Buddha's Law makes clear the causal actions committed in the past. The Parinirvana Sutra states: "Good man, because people committed countless offenses and accumulated much evil karma in the past, they must expect to suffer retribution for everything they have done. They may be despised, cursed with an ugly appearance, be poorly clad and poorly fed, seek wealth in vain, be born to an impoverished and lowly family or one with erroneous views, or be persecuted by their sovereign. They may be subjected to various other sufferings and retributions. It is due to the blessings obtained by protecting the Law that they can diminish in this lifetime their suffering and retribution."
