With sufficient technology anything is possible. So, let us assume heaven is possible. Why not? Limitless utopia mixed with immortality. Why not? The question is: do humans have to create it? Or did someone else in the infinite multiverse do that already?
Positing what has been called "Heaven" is no different than positing nonlocal dimensions higher than our own -- which we have known to exist for decades. If physics can quantitatively point out higher dimensions and the inflationary multiverse, how radical is it really to suppose that beings existing on a fundamentally different frequency, with powers that we do not possess nor understand, can exist? Isn't the cosmos big enough and interesting enough for that? Is consciousness really restricted to the human mind?
As Robert Anton Wilson and others have noted, if one really looks at the UFO evidence objectively, it is very difficult (if not preposterous) to see these "contactees" as merely having random, disjointed hallucinations. There is an ordering, a hierarchy of patterns involved with what these people report. Moreover, frequently the phenomenon is shared by multiple people (sometimes up to hundreds of them). You've got to admit, at the very least, that some coherent phenomenon is causing a whole crowd of people to "hallucinate" the same thing simultaneously. The dogmatic materialist's insistence that these happenings are merely delusional and should be shunted off to the garbage pile of worthless information just doesn't fly at all when one looks into the actual evidence -- trustworthy compilations of evidence by impartial and intelligent investigators. There is clearly something more going on than rednecks rambling to tabloid reporters. Whether we need ESP, or the Jungian unconscious, or synchronicity, or non-local transmissions from deep space to explain these phenomena, who knows. (God knows most people aren't ready for that kind of thinking -- especially the dogmatic materialist). But there are orderly phenomena surrounding these UFO mysteries, and have been for decades if not centuries. There are patterns, and independently verified evidence of correlations. The question should not be "do you or do you not believe in aliens?" but rather "what is the causal factor in these seemingly disparate but definitively related UFO claims?" What is the psychological and neurological reality? Probably not what most people think...
Even the most wildly implausible supernatural forces or unknown phenomena are, if real, physical phenomena. If Heaven exists, it does not exist outside of a physical and knowable framework. Elements of the supernatural exist in nature. If physics were to progress another hundred years, things we regard now as magic(k)al and utterly fantastic would be scientifically understood and yesterday's news.
The universe saves everything. Continued existence of form and content is only a question of retrieving and interpreting the information. The wave function doesn't disappear, that information never goes anywhere. Nothing is ever lost. This is inescapable.
You cannot escape not escaping.
Whatever is not in spacetime does not die.
At the atomic level there is no such thing as death.
The thing about Buddhism is that it stops itself artificially short of real places that the spiritual practice can take people. This was a deliberate and intentional move on the part of the Buddha Gautama to disrupt and dispel people from focusing on any matters other than the purely Earthly, here and now. Buddha even acknowledged the pantheon waiting at the gates leading in from the Void, and felt strongly that a singular focus on Bodhisattvahood on Earth was the most important thing -- so important that he ignored and denied the truth in favor of it.
Humanity is recapitulating with technology certain large realities that already exist, but doing so in a new, artificial medium. Such as: telepathy; collective networks of minds; information saving; transdimensional awareness and computation; and immortality, to name a few.
The superposed wave function that constitutes one's consciousness can not only be localized at the body, but can extend indefinitely beyond the body, and even in principle leave the body completely (potentially to return, or not) and remain intact.
What made Castaneda's books so popular was that they presented the supernatural as existing in reality. Only it wasn't real.
Some especially interesting things happen on this Earthly plane, but no one would believe them except the people to whom they have happened, so it is not common knowledge.
If there's one thing I'm pretty sure of, it's that higher realms are a lot like this world in several respects -- there's politics and power struggles, fighting, alliances, corruption, dishonesty, jealousy, duplicity, pettiness and any number of other things that make people wince about this world.
Let's say you're a being in a higher realm, outside of the cycle of birth and death. Would you decide you wanted to reincarnate again? I think not. Reverence for the truth is what it is all about.
We may have our problems in physics, but compared to the rest of what is, this realm is child's play.
I'm not sure God could control things "down here" even if He wanted to. Fix a leak here, and then a new leak springs there, and a new one over there, and pretty soon there are so many leaks that you would have been better off not doing anything. So I don't think he's in a winning position to "fix" our various and sundry major problems. Only we can do that. I think blaming God is unfair to Him and simply an error on our part. He is vastly powerful but perhaps not truly omnipotent.
The technology to upload and preserve souls already exists -- so why is humanity so hell-bent on re-inventing it?
Whether or not there are a God and/or some type of heaven, most people here on Earth are believers because they expect some sort of reward in a paradisiacal afterlife. And, additionally, they don't have much of a problem with sinning regularly in most cases. That's not especially copacetic.
Whether or not it is real is irrelevant; too much emphasis on the afterlife is strongly inadvisable as it leads to the wrong attitude and wrong living.
Live when you can.
A broader picture of reality has emerged for me over recent years, i.e. that there is a fuck of a lot more going on here than any of us realizes.
Our universe seems to operate with a pattern of singularity very much in mind. There are gravitational singularities (black holes), technological singularities and existential singularities (the end-of-life events).
Contrary to atheist-materialist dogma, the miserable muck down here on Terra is not all there is.
Has the future happened already? An infinite number of times? Is Heaven a future that has already come to fruition? Is our future state interacting with us backward in time? We are indeed creating a reality in which superpowerful artificial intelligence will be our offspring, who will venture out into infinity, and who will have uploaded our souls to perpetuity. Isn't this heaven? Isn't this utopia? It is happening, and it is not remotely absurd to suggest that in the vastness of the multiverse, it has happened already. So.... is it really all that inane to posit heaven? To posit the transmigration of souls -- or in less objectionable parlance, minds which have been uploaded into an all intelligent, godlike matrix? It must have happened already, a trillion times.... That is the infinite....
If hell is possible, then it exists somewhere. If heaven is possible, then it exists somewhere.
If there is an afterlife, all that's waiting for us is hard work.
John Lilly's ECCO strikes me as real.
Human consciousness of reality is a fictitious virtual reality simulator inside one's skull. If technology develops to the point where any sensation, any real scenario can be generated and lived out -- and there is no reason to suspect that it will not -- it will not be any less real than anything else humans have ever done in their native or semi-native settings. The same could be said about an afterlife if you believe in one. It would not in truth be any less "natural" than nature itself.
Telepathy is a plain fact.
With sufficiently advanced technology, everything that ever has happened, and everything that ever will happen in this universe can be observed.
Our reality is a subset of a much higher and larger reality -- but it is still a reality.
It's not all sunshine and holding hands and rainbows in the greater existence. The 'peace and love' view is naive and vulnerable.
The universe doesn't have to be deterministic for a being from a higher dimension to be able to see all of the future.
There are many gods, but only one most powerful one. It's elementary.
The dead envy the living their lives, but much as childhood to a child is nothing special, so life to an adult human is not in most cases, in most places, viewed so positively. I suppose we rarely appreciate what we have until it is gone. Life is not so special for the majority while they are alive. So wanting it back may be an idealistic error.
Reality doesn't stop at eight circuits. The multiverse is like a giant, vibrating brain with a multitude of circuits. The higher circuits -- really, the eighth and above -- constitute what we have come to know anecdotally as "heaven." And we should conceive more intelligently of how we perceive the circuits. We think of the first as the "lowest," the first. But really, it is the furthest outgrowth from the source that there is. Don't let time confuse you. Eukaryotic cells are further from the source than a woman yodeling, even though they came first in the subjective course of time. Eventually, the multiverse will come into focus.
The higher realms are real. If science were advanced enough, it could explain them.
It doesn't take a lot of imagination to realize that beings with sufficient technological knowledge could have access to any given information, at any given time, throughout the universe.
I think the subquantum realm exists in a higher dimension, and that definite things are occurring there.
The best monks get higher than any drug, with perhaps the exception of DMT. And of course they are able to remain there for extended periods.
