I also posted this on E-Sangha.
While reading up on some information concerning the coming Buddha Ariya Metteya, I came across the idea of the "world cycle". Of course, I've heard of this before in Buddhist cosmological teachings, but I never really pondered it until now.
It is said there will be a total of five Buddhas in the current world cycle, Metteya being the last. Thus, beings must practice rightly and aspire to meet Metteya Buddha during his sasana before the current world cycle is complete. Beings not attaining Enlightenment (or, in Theravada practice, the first stage of Awakening) before this world cycle expires will find it incredibly difficult to do so afterward.
What do you all think of this? Where can the idea of the "world cycle" be found in the suttas? Do beings trapped in samsara wander from one world cycle to the next, or does something different happen to them when this world cycle ends? How long does a world cycle actually last?
I look forward to everyone's responses.
