This is a short quote from some of my current reading that I find irresistible and fascinating. I did not write it and credit is given below in footnotes.
Consider for a moment: All that we do and are can be seen and viewed by beings so much more powerful than us? Every secret is eventually told or revealed. I find that humbling and perhaps if we all reflected on this, we would be more inclined to be on our best behavior at critical times. As Emerson once said: "The Great God sells all things at a fair price!"

"Though paradise is not visible to the eyes of most mortals, nevertheless it is real. There was a time when people would have dismissed with utter skepticism the idea of radio and television transmissions in the ether, but now billions hear and see them daily. Likewise, any devotee can tune in the celestial sights and sounds of the angelic realms through the soul's powers of super-audition and super-vision, when by meditation the inner relevision and heart-mind radio are free from the static of restlessness and mortal desires...."

To "see heaven open," as expressed by Jesus, is possible in two ways: (1) By removal of the vibrations of etheric space with its boundary walls of light through the command of the Ultimate Intelligence. (2) By overcoming the limitations of the physical eyes and penetrating the spiritual eye of omnipresent perception."*

*Since the divergence of science and religion in centuries past, scientists have typically greeted the idea of "higher dimensions" with skepticism. At the forefront of advanced physics today, however, is the theory of superstrings--a theory that not only allows for additional dimensions but requires them, writes Brian Greene, Ph.D, in "The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory" (New York: Vintage Books, 2000).

Furthermore, reports Los Angeles Times science writer K.C. Cole, scientists acknowledge that cosmic forces may well exist in the other dimensions required by string theory. "If so," she writes in "The Hole in the Universe", "they could have far-reaching effects, and perhaps even explain some of physics' most difficult puzzles."

String theorists explain that we don't detect the additional dimensions in the universe because even though forces emerge from them, spatially they are tightly "curled up" to almost infinitesimal size. Other scientists, including William Tiller, Ph.D., professor of engineering at Stanford University, maintain that higher dimensions remain invisible not because they are small but becuase they are "inaccessible to the physical sensory system, or to our present day instrumentation."

A proposal that is all the more remarkable in that it comes from a Nobel Prize winning physicist has been put forth by Prof. Brian Josephson of Cambridge U., renowned for key discoveries in subatomic quantum mechanics:  "....If we follow this path of synthesis of science and religion (using meditation as an observational tool), what we are doing is using our own nervous systems as instruments to observe the domains in which God works. Ordinary scientific instruments like telescopes, galvanometers, and particle detectors are not going to be good in this context because they are designed to function in the material domain. Our nervous systems, on the other hand, are designed to allow us to interact not only with the material level, but also with the spiritual levels... All the different levels are open to exploration if we develop our nervous systems so that they tune in. One can imagine that this would be a part of scientific training of the future."
