It might be relevant to point out, that bringing anything that doesn't fit into a relative box to a consistent condition and then to build a relative box around it would be elusive but more importantly insane.
Certain things might seem self evident, such as your name being Tim, (after having mentioned it more than once) and no one having an experience contrary to that.
No matter how many NDE's are reported the personal experience of someone who hears about them may not include any spiritual insight or experience of their own.
Someone once said you can lead a horse to water but you can't make it drink, being that the horse will make the decision from its own experience of whether or not it is thirsty and likes the source of water.
Out of body possibilities would seem to be a subject regarding the spiritual aspects of the mind not bound by the physical body. To lead the intellect to a threshold or boundary that it believes it cannot cross will not necessarily allow it to believe there is anything on the other side if it has no experience or if it isn't willing to stretch beyond the boundaries of the box.
In the Spiritual Teachings of history the relative boxes of the intellect are constructed through belief, they exist because of the consistency of thought and experience, not because they must but because they can exist and someone chooses to reflect that limitation in thought and experience.
The barriers between the physical and spiritual cannot be broken if the intellect refuses to accept anything different and so there has always been a gap between the spiritual and physical world in the intellectual understandings and relative boxes of human beliefs. This doesn't mean the barrier is real it just means it is made to be real in the mind.
An adult lives in a different world than a child, but it does not mean there are two worlds for the child and adult coexist in perception of time and space. Children have built fewer beliefs in their patterns of thought than most adults and are less likely to say something can't be done out of habit and the experience of reinforcement of habitual thought.
If you go to a foreign country where there are different rules and habits you will find cultural barriers that would seem to differentiate the two countries experienced and separate them but if you step back far enough you will only experience a rotating sphere with a civilization in progress or lack of...
The nature of life as it is contained within the individual is like a set of clothes worn while visiting a container of thoughts and beliefs. The nature of the spirit is without the limitations of its clothing and so to look for the essence of the thoughts while wearing the clothes would be similar to trying to find yourself in the jeans you wore last year. You are what you are always or what you are while wearing the jeans or what you wear now.
You could try to isolate yourself to a single moment and say this is all you are, but you might find yourself experiencing something different in another moment in time.
Consciousness is much more than a set of conditions and experiences and to build a device in a relative world to exceed its limits of being is sort of like the search for the grail. Immortality is what powers the faith in humans to seek proof of the afterlife and to squash the fear of death. But consciousness that is immortal already lives without death and so to stand on one side of the fence and imagine the other is the imagining of illusions.
You yourself have created both sides from a power of greatness far beyond the illusion in the first place.
It's like climbing down a ladder to a basement and forgetting the upper world, and then trying to imagine what the upper world looks like and feels like while totally ignoring the fact that you descended in the first place.
While convinced that you and the basement are real you attempt to resurrect the upper world in the basement with the tools that only exist in the imaginary basement you created.
It's definitely the long way around the barn.
