bridge,
I think you misunderstood my profundity.
The human imagination has perhaps no limits and it is this ability that allows it to conceive of impossible conditions, such as the scenarios often shown in cartoon movies. My implication was not that an alleged spiritual world is impossible but that within the scope of human imagination only a small number of scenarios map to reality. The only way we can distinguish between something imagined and something real is direct physical evidence. There are many things that man has imagined that seemed impossible but were later found possible, walking on the moon for example.
But while some things imagined map to reality or might map to a reality it is not true that everything imagined will acquire such a mapping.
As for the spiritual world not being part of "reality".
Note that I didn't say that. My point is that you have no way to know whether an alleged spiritual world is real or imagined.
When you are away from a loved one for a period of time and you think of them, is the mental image you draw up not "real"? Perhaps someone you love very much has passed on, or is ill, your memories are now, your emotional status is very up to the minute. Then why do you feel what is described as "heart sick"? You mean to tell me those feelings are not REAL?
Emotions are real and physical, why try to equate them to something immaterial and supernatural?
The spiritual world is real.
If you think spirituality is the manifestation of human emotions, then you are of course free to use such an inaccurate label. But otherwise what is your criteria for such a claim beyond your imagination and an apparent misunderstanding of the nature of emotions? All physical evidence indicates that emotions are primarily the result of neuronal and hormonal processes. Do you have real evidence to the contrary?
The fact that you require or desire physical evidence to satisfy some criteria of its existence only means you lack development of the ability to sense it.
If you can therefore "sense it" then presumably you have access to some physical evidence that I do not, or are you claiming that you have additional senses that will mean I can never 'sense' this alleged thing? Either show your evidence or demonstrate the existence of your extra senses. Unless that is forthcoming you have nothing other than your imagination as a basis for your claims.
The reality of the physical world is what you make of it.
We should distinguish between absolute reality and reality that we can observe. What we can observe is most certainly just a subset of the total. But without observation we can make no reliable statements about anything else. Claims concerning anything we cannot observe might be true or more likely will be false since there is probably an infinite number of things we can imagine but only a tiny finite number of things that we can imagine that also map to a reality. Without a direct observation you cannot know if your claims have any basis in reality.
The reality of the spiritual world isn't much different.
Except that for the moment it is in the infinite set of imagined items that cannot be observed and for which there can be no justification for claiming a truth.
While it maybe equally difficult for someone to grasp the idea of a spiritual world outside this physical world, it certainly doesn't render it impossible.
I am perfectly capable of imagining such a realm, it is not difficult by any means, in fact it seems that it is so easy to imagine that even the uneducated and people of low intelligence can imagine it. But I never claimed it was impossible but no one has yet shown that it is possible let alone real.
