Just wondering, since enlightenment is the cessation of all suffering, were there other people or beings that had achieved that and were contemporary to buddha. One such candidate may be the Jain leader Mahavira - he is said to have achieved not only freedom from suffering but also omniscience after that. This is just one person, there could have been many others who were fully enlightened but not teaching maybe sitting in a cave or something; especially when one thinks that Buddha himself after his liberation was considering that.
So it seems to me a little bit surprising that buddhas have such long waiting period In between them appearing on earth. Did buddha himself resolve this, or comment on anything like this? On the same theme, where did the prophecy of Maitreya-buddha come from - was it shakyamuni-buddha himself who foresaw that? Thanks
