(2) There are two kinds of cultural relics, namely, bone relics and Fa Song relics. The Merit Sutra of Washing Buddha regards the Buddha's remains as Buddhist relics, and the teachings left by the Buddha are called Buddhist relics. This kind of relic shows that after the Buddha's extinction, the teachings and precepts mentioned by the Buddha will last forever and can be relied on by all living beings, so it is called Fasong relic, or Fasong relic for short.
(3) Bone remains, hair remains and meat remains. Volume 40 of Fallin says that the bone relic is white, the hair relic is black and the meat relic is red.
