Then follows a Universal Cycle (=Aeon=kappa=kalpa) empty of Buddhas!
In that
aeon humans will act like animals or worse. Incest & cannibalism will
be the rule of the day. Terror, wars, death & agony! So make effort NOW!
Then in the next eon 2 Buddhas will emerge: First Rāma and later Dhammarāja
Buddha Dhammarāja was king Pasenadi of Kosala at Gotama Buddha's time.
