The "Mirror of Reflection" was built to make the dead see their sins, such as having weak faith in the Buddha, the founder of the world religion of Buddhism.
In the first hall, the "Mirror of Reflection" lets the dead see their own sins. Sins specifically mentioned include: mocking or disbelieving the tract itself, taking one's life without good reason, having weak faith in the Buddha, being careless as Buddhist or Taoist priest, killing live creatures, stealing, cheating, gambling, drinking, drowning baby girls, killing slaves etc. Yan Luo himself rules over the fifth court of hell; the Highest God demoted him from the first court because he proved too compassionate towards murder victims, allowing them to return to the world for another life. He is revered as the founder of the world religion of Buddhism, and worshipped by most Buddhist schools as the Enlightened One who has transcended Karma and escaped the cycle of birth and rebirth.
