Learn about Truths & Myths Revealed:
Ah, this is a most complex area. But we will attempt to answer in simplicity. So as to the first question: Throughout the past 3500 years, especially peaking in medieval times, possession was thought to be a very real phenomena, and in fact, portions of your churches had specialists who were dedicated to the removal and casting out of demons and devils. Not only were Christians taught to be fearful of such ‘evil entities’ but certain indigenous groups and pagan groups also accepted this belief.
That you term ‘evil’ does indeed exist in duality, it is a function of free choice. Your history records many horrific wars and inhumane dictators and leaders who have enacted catastrophic atrocities. In your terms these men were evil.
The earth is a duality planet with the complete requisite electro-magnetic spectrum in 3d that contains by definition a positive and negative field.
But understand this, no real demons or devils exist other than the ones you create in your thoughts and beliefs in duality. But negative thought-forms are indeed created through your own fears and angers that can amass into varying degrees of independently aware negative energies. Such is the power of thought. Because your planet contains both spectrums there are indeed energy forms that amass in the ‘negative’ field and when encountered they feel quite imbalanced and quite opposed to ones optimal sense of well-being, but at its core this is electrical and not demonic.
Now, there are certain Devic energies that are within their electrical nature of the ‘negative’ end of the spectrum. There are also fields of electrically negative energies that naturally occur , and are part of the spectrum that balances what you would term ‘positive electrical fields’.
But understand from the truer perspective and higher aspect, none of these are truly demons, none of these can truly ‘possess’ you. However these can and do attach to auric fields that are open due to human EMF (Auric) circuitry malfunction. Indeed in many cases it is the very fear of these that opens your field and allows these forms to attach. That is why it is vitally important to understand how to maintain your etheric electro-magnetic field or Aura.
