The notion about the psychic power can't be understood without certain basic concepts.
The psychic history is very complicated and most of us still don't know what they really are.
First we have to trash the idea that anything can be done by the means of their supernatural power.
Nothing can trounce the natural law we go by.
But again, we can't say like the materialists that every single thing in this earthly world can be explained by science.
As the ancient perception teaches us, there is certainly a lot more in this universe than we can discover by our sense or intelligence.
This corporeal universe is an expression of a gigantic and visible or invisible monarchy, filled with many classes of conscious existences.
What they do together day by day is called the laws of nature, but here we might interpret it as habits that has grown in the nature, nothing out of ordinary and going on believing just what we can see or can feel.
But there is some controversial so called spiritual energy that regular people can't explore with their organic senses.
The spiritual energy in one is made of the mind and emotions which is called Psyche.
Our psyche is not wholly developed as we can't distinguish the invisibility of a portion of world around us; but it should be kept in mind that invisibility of certain things doesn't involve spirituality.
The one who can explore these invisibility through a controlled self -psyche, can achieve the extraordinary Psychic powers in cases.
In the psychic world, the lower mind of people unnaturally works.
But the lower mind is mostly uncontrollable and we ourselves can't understand its functioning.
The atypical growth of psychic nature within someone is a very rare case therefore.
Psychic forces are merely neglected science of human soul in this world.
