This subject is amusing yet some of it is true. Some are born with the gift to see as Shaman, only because they were granted the gift. All others who practice this art is known as Sorcery. Usually, a very deep understanding of this can be traced back to ancient Babylon where magic and Sorcery takes place when the fallen angels taught men how to open portals. The different dimensional planes are not meant to interact but because of this knowledge from the fallen angels, it could be done. The ones who were taught this opening of portals also had to be very well taught, yet some failed because they could not and did not have the strength in spirit to overcome what was behind the portals. That is why this is a hush hush subject and as you can see, not too many people like this subject or are writing about it (checkered flag floors with black and white tiles is one example where this occurs).One reason why the Jews keep the secret since ancient Babylon time is not because they want it for themselves but they knew that man's heart is weak, and that in order to be a student of it, you had to be highly trained. Man's heart was to search for the Truth, and that meant it had to know both the good and the bad; life and death, light and dark, the duality nature of cosmic spiritual planes. That is why all things taught by Jesus aka Yahshua was mainly focusing on the spiritual aspect. When these portals are open, it was also open to demons within oneself, demons of wickedness and evil, the every duality essence of life and preservation of LOVE that we are all taught to live our lives by. In the Bible, these demons do exist and it could easily be seen with the story of King Saul, who was tortured day and night by those demons. He hated David because King Saul wanted power for himself, his position as King allowed for him to see and read all scrolls whether political, religious or spiritual. Some scrolls include pronouncing "words" or phrases to conjure demons so that you can use them for personal gain, but in return these demons could live among you. That is why in the Hmong culture and tradition, there is always a "Dab" or Dlaab for everything. These demons can not just come and dwell on their own, it first must be conjured up, provoke and then allowed. It is even fed and worshipped since it was able to perform what the master wanted, but little do they know, the demons are much more then mere servants, its the soul that is at stake here. For mortal men are eager and ambitious for worldly matters. Humans who are born from the wound of women are "free souls". Meaning they chose their own path, hence righteousness and freedom. When they die, they won't be resurrected in the spirit unless they are reborn again, meaning they have taken the spiritual awakening in themselves. They have believed that without the Creator, they can not arise by themselves. The Quran especially talks about this in details. When everyone has died, only One will remain standing, and that is "GOD" itself. Satan and its minions knows this very well, as they are in the spiritual plane, they can no longer die a physical death but that they are cast in the lake of Fire for eternity. Satan and the demons take on soulless human flesh teaches that all humans will be resurrected again but this is simply not true. You cease to exist if you are not spiritually awaken. Humans who are awaken spiritually will be in spirit form and in that plane. They can no longer die like the fallen angels, and they chose their path...once they have seen the whole truth they would have to chose the way of Satan, who think itself is god or to be with GOD, who is their Redeemer and Savior. The greatest test is LOVE. So you see, it is a spiritual warfare and principalities are tested. He who chooses wickedness (the twisting of TRUTH) and death shall receive it and he who chooses Life shall receive it accordingly. Choosing Life means that it will take you an eternity to learn about "GOD" and that is another chapter to be learned, not for our physical flesh to dwell because our "eyes" have been pulled over by the vail, even as we have eyes, we can't see because it was written, "let the blind lead the blind" and "let the dead bury the dead".
