As I discussed in another entry, falsehoods are the main M.O. of evil, so our interest in truth inevitably protects us from evil. Of course sometimes we cannot distinguish based on only using our mind, depending on the information we have, which is why the heart is so important. If truth and falsehood relates to the mind, then in the same way love and apathy relates to the heart. Hate is actually not so much the opposite of love because first I'm not talking about the emotion, and actually when you think about it love and hate in that sense involves emotional entanglement, whereas complete disconnect would be the complete opposite of love, rather than just the direction of the energy. It has been said that if love in this sense was completely absent the world would turn to dust, so this really goes much deeper than interpersonal dynamics, too.
Now we can see how the dynamics of evil plays out in a divisive pattern with lies and apathy. Again if love is the force that holds things together, then the opposite would be to divide - divide and conquer. If love is the natural state of the created world, then you have to lie about it in order to get people to behave otherwise. In fact, not only are people separated from nature, so much so that their mental and physical health suffers on a mass scale, but they are also divided within themselves. One of the most important ways this shows up is how the mind is largely separate from the heart. It's interesting to note that in Buddhism the mind is considered a sense organ along with the other five, and they speak of the heart-mind as if it is one thing. But of course we know of many examples where some people are a lot of brain and little heart and vice versa.
So of course the question is why would people believe the lie? I would say it is largely because they favor one faculty over another, whether it's the heart or the mind. If we look at it from the perspective that the two are supposed to be one in the first place, then the fact that so many people are biased one way or the other would mean they are not fully functional - they either cannot think critically or they lack the instinct that would recognize when there is an absence of love. After all, if it is a universal cohesive force then it should stick out like a sore thumb if it's missing - but we have an entire culture that has promoted divided individualism from the time we were born, and it would be foolish to dismiss the profound effect this has had on our consciousness.
What does this have to do with dealing with hauntings and supernatural entities? Everything. Tools and techniques certainly all have their place, but without recognizing that they need to be based on these principles you really are ignoring the nature of evil in the first place. It would be one thing if you are just bothered by the lost soul of a ghost, which is essentially a situation based on ignorance, but if evil is in fact involved how can you even begin to deal with it if you don't understand what it is you're dealing with? And here is another important point: Evil takes advantage of ignorance. When we look at the manifest evil in the world in terms of mans inhumanity to man, or the ridiculously rampant greed that is being revealed more and more, what do they do? They take advantage of the average mans ignorance. The thing is, if love holds things together, then by its very nature you are tapping into something much bigger and supportive on a universal scale. But if you think some special technique or a special person is the only way it would work, then your attention is already separated from this vast field. It's true sometimes specific things and certain people do play a key role in specific situations, but how do you suppose you connect with that solution in the first place? One may find synchronistic timing, which makes sense BOTH intuitively with the heart as well as the mind, but is it likely to be a result of only intellectual research or just feeling our way around without any kind of critical thinking?
