Much is made of multiple dimensions. There are only 3, with time a possible 4th. The Spirit realm is not a different dimension, but rather a change in form, from physical matter to an energetic state. Remember the only thing complicated about the universe is Man’s perception of it.
A message from my Spirit Teacher, Gene.
OpEd: Our minds imagine and conjure up so many wonderful things. Most of which never come true and are delusional. The scientific process allows for any hypothesis, theory or speculation which must then be proven to be correct through scientific and mathematical process. Many speculations stand as unproven truths for long periods. But the are none-the-less, not true.
In the realm of Spirit, ESP and the paranormal too many accept speculations and falsehoods without a second thought. As such, too many times people are led down false paths with theories which will never be proven accurate. Your biggest defense against these types of falsehoods is your own awareness. Once you develop and trust your intuition and Spirit Communication you will no longer have to accept on face value something that is poetic but not at all a spiritual truth.
Many people feel I am too negative about the abilities of other psychics and mediums. I can see why some people may feel this way. No one likes to feel they have been lied to or taken advantage of by another. In many cases, the lies are unintentional but lies none-the-less. Before judging my judgements, develop your awareness and see for yourself what it is I see.
