'But now I have seen you, maker of this house; never more will you build again. All the rafters are broken and the ridge-pole destroyed. The fever of life is gone and all desires are past, for my mind has reached the eternal Nirvana."
“Behold, O monks, this is my last advice to you. All component things in the world are changeable. They are not lasting. Work hard to gain your own salvation.”
Then the Buddha lapsed into the jhana stages, or meditative absorptions. Going from level to level, one after the other, ever deeper and deeper. Then he came out of the meditative absorption for the last time and passed into nirvana, leaving nothing whatever behind that can cause rebirth again in this or any other world.
Then the Blessed One, emerging from the cessation of perception & feeling, entered the dimension of neither perception nor non-perception. Emerging from that, he entered the dimension of nothingness… the dimension of the infinitude of consciousness… the dimension of the infinitude of space… the fourth jhana… the third… the second… the first jhana. Emerging from the first jhana he entered the second… the third… the fourth jhana. Emerging from the fourth jhana, he immediately was totally Unbound. — DN 16
Smiling at us from the grave, do we know that Buddha actually attained non-existence?
I mean, they say his life was “complete” he can rest easy that he left his teachings and disciples in the world. But look at the world. Jesus failed, and Buddha failed, in fact the world is worse today than when they left it. Now China is some stupid dictatorship that even polices religion. Next thing is mind-control. How can Buddha rest easy, knowing about the parasite of the human race still lingering in the galaxy?
Now let as assume that he did rest easy, that he did infact reach Nirvana and had no ego no lust no attachments no desires when he passed.
How do we know that this alone is enough not to rebirth? Many buddhists say there are still incarnations of Buddha, but perhaps what they mean is they have the personality of Buddha but a different sentience. Still though, what scientific way is there of knowing that Buddha did not reincarnate? What spiritual way of sensing Buddha did not reincarnate? Can it be verified scientifically? Can it be verified spiritually?
