Although some sutras assert that the decline of Buddhism is accompanied by social unrest and natural catastrophe, such as "Hometsujin-kyo Sutra" (Decline of the Law Sutra), it is generally believed that these are bogus sutras that were created in the later stages of history.
なお、仏法の衰退と共に社会情勢の不安や天変地異も説く『法滅尽経』などもあるが、一般的にはこれは後世になって創作された偽経とされている。
