How could we
first show that an entity that resided in another dimension far beyond our reach had objective existence?
Do you understand the problem? The GPS tracker does not extend that far.
No, I have not read that but it sounds interesting. I don't think it is a myth. I am certain that other dimensions beyond this dimension exist.
Of course, I could never prove that but it is not based on proof.
An interesting book that talks about the spiritual world and the many spheres of existence is called
The Afterlife Revealed.
This is not a Baha'i book, but it is congruent with what little has been revealed about the afterlife in the Baha'i Writings.
"At the very foundation of religious faith and hope is a belief that consciousness will survive death and that we will live on in another dimension of reality. But that foundation easily crumbles when scientific minds are unable to wrap their brains around an afterlife, when they are unable to visualize a non-material world. As the foundation gives way, the philosophy of materialism takes hold and gives rise to moral decadence, egocentricity, hypocrisy, hatred, disorder, flux, strife, chaos, and fear. Such seems to be the state of the world today. There is so much to be found outside the highly guarded boundaries of mainstream science and orthodox religion for those willing to open their minds to it, for those willing to recognize that the dissemination of Truth did not stop with the good books of organized religion and cannot always be found in the laboratory.
Beginning in 1848, a number of sensitive people began developing as mediums, bringing forth communications from the spirit world. One of the skeptics investigating the "popular madness" was Professor Robert Hare of the University of Pennsylvania. Intending to debunk it all, Hare would, after extensive research, become a believer. When he asked an apparently advanced spirit what it was all about, he was told that it was "a deliberate effort, on the part of the inhabitants of the higher spheres, to break through the partition which has interfered with the attainment, by mortals, of a correct idea of their destiny after death." Unfortunately, both orthodox religion and mainstream science, acting out of ego and fear, have rebuked the efforts of those inhabitants of the higher spheres to enlighten us, thus permitting the foundations of both faith and hope to further crumble.
In
The Afterlife Revealed, Michael Tymn sets forth some of the most credible messages from the spirits relative to the nature of their world. Instead of a heaven-hell dichotomy, we are told that there are many levels, or as Jesus is quoted, "many mansions," and that we cross over to the "other side" based on what might be called a "moral specific gravity." We discover a Divine plan - one of attainment and attunement, of gradual spiritual growth, of evolution of spirit through progressively higher planes. We see how we are really souls occupying bodies rather than bodies housing souls and how our souls are progressing in finding their way back to Oneness with the Creator through the challenges, the adversities, the trials and tribulations offered us in a particular lifetime."
